6. DNApropertyRun
Calculates structural and physical properties of the DNA molecule. These properties
are used in the DNA Atlas representation on the Genome Atlas web pages. Properties include
Intrinsic Curvature, Stacking energy, position preference, various repeats etc. (please see
below for documentation). Use operation ‘pollQueue’ to poll the status of the job.
Input:
* ‘method’ : Calculation method, specifying which result are to be generated,
e.g. ‘Intrinsic Curvature’ (see documentation below)
* ‘sequence’
* ‘id’ : Sequence identifier
* ‘seq’ : DNA sequence
The following DNA properties can be calculated:
Intrinsic Curvature
DNA curvature is calculated using the CURVATURE programme (Bolshoy et al. 1991, Shpigelman
et al. 1993). The term curved DNA here refers to DNA that is intrinsically curved
in solution and can be readily characterised by anomalous migration in acrylamide
gels. There are different models for curved DNA (Sinden et al. 1998), although the
predictions for curvature fragments largerthan a few hundred bp is essentially the
same (Haran et al. 1994). The scale is in arbitrary “Curvature units”, which ranges
from 0 (e.g. no curvature) to 1.0, which is the curvature of DNA when wrapped around
the nucleosome. The scale used for this atlas ranges 3 standard deviations around
the mean.

Position Preference
– a trinucleotide model based on the preferential location
of sequences within nucleosomal core sequences (Satchwell et al. 1986). We use the
magnitude (e.g.absolute values) of the trinucleotide numbers as a measure of DNA
flexibility (Baldi et al. 1996). The trinucleotide values range from essentially
zero (0.003, presumably more flexible), to 0.28 (considered rigid). Since very few
of the trinucleotide have values close to zero (e.g. little preference for nucleosome
positioning), this measureis considered most sensitive towards the low (“flexibity”)

positioning signals in human exons and introns. (1996) 263:503-510
Stacking Energy
Base-stacking energies are from the dinucleotide values provided by (Ornstein et
al. 1978). The scale is in kcal/mol, and the dinucleotide values range from -3.82
kcal/mol (will melt easily) up to a maximum value of -14.59 kcal/mol (which would
require more energy to destack or melt the helix). (All 10 values are listed in the
table below.) A positive peak in base-stacking (i.e., numbers closer to 0) reflectsregions
of the helix which would de-stack or melt more readily. Conversely, minima (larger
negative numbers) in this plot would represent more stable regions of the chromosome.
Dinucleotide melting energies in kcal/mols:

function for the calculation of nucleic acid interaction energies. I. Base stacking

Protein Deformability
“Protein Induced Deformability” dinucleotide values are from protein induced deformation
of DNA helices as determined by examination of more than a hundred cr et et al. 1997al
structures of DNA/protein complexes (Olson et al. 1998). The dinucleotide values
range from 2.1 (the least deformable dinucleotide), to 12.1 (i.e., the dinucleotide
step (CpG), which is often deformed by proteins). Thus, on this scale, a larger value
reflects a more deformable sequence whilst a smaller value indicates a region where
the DNA helix is less likely to be changed dramatically by proteins. The average
protein deformability value in the entire E. coli K-12 genome is 5.12.
* Goffeau et al. The Yeast Genome Directory (1997) 387 (supplement):5-105
* W.K. Olson and A.A. Gorin and X.J. Lu and L.M. Hock and V.B. Zhurkin DNA sequence-dependent
deformability deduced from protein-DNA crystal complexes. (1998) 95:11163-11168
Propeller twist
We use propeller twist as a measure of helix rigidity, since the propeller twist
angles have been shown to be inversely related to rigidity of the DNA helix in crystals
(el Hassan et al. 1996). Thus, a region with high propeller twist would
mean the helix is quite rigid in this area, and similarly regions that are quite
flexible would have a low propeller twist. Propeller twist values were obtained from
cr et et al. 1997allographic data (el et al. 1996), with the exception of the TA
step, which was taken from a theoretical estimate (Gorin et al. 1995). Plots using
other sets of propeller twist dinucleotide values were very similar (data not shown).
The average propeller twist value in the entire E. coli K-12 genome is -12.63 degrees.

morphology. (1995) 247:34-48
DNase I Sensitivity
DNase I values are based on experimentally determined trinucleotide values (Brukner
et al. 1995, Brukner et al. 1995). These values are reflectiveof the anisotropic
flexibility or “bendability” of a particular DNAsequence. The trinucleotide values
range from -0.280 (rigid) to +0.194 (very “bendable” towards the major groove). Smoothing
over a large regions, (which is necessary for viewing entire genomes) tends to smooth
out differences in bendability. The average DNase I (“bendability”) value in the

Palindromic hexamers
For a given sequence, any palindrome of 6 nt (e.g., AAATTT) is given a value of 1,
while all bases not included inpalindromic hexamers are given a value of 0 (van et
al. 2003).

G Content
The “G Content” of a given sequence is merely the fraction of G’s in a given sequence
(Jensen et al. 1999). It can range from 0(no G’s), to 1 (all G’s). For a sequence
that is 50% AT content, one would expect roughly 25% G’s.

(1999) 150:773-777
A Content
The “A Content” of a given sequence is merely the fraction of A’s in a given sequence
(Jensen et al. 1999). It can range from 0(no A’s), to 1 (all A’s). For a sequence
that is 50% AT content, one would expect roughly 25% A’s.
* L. J. Jensen and C. Friis and D.W. Ussery Three views of complete chromosomes
(1999) 150:773-777
T Content
The “T Content” of a given sequence is merely the fraction of T’s in a given sequence
(Jensen et al. 1999). It can range from 0(no T’s), to 1 (all T’s). For a sequence
that is 50% AT content, one would expect roughly 25% T’s.

C Content
The “C Content” of a given sequence is merely the fraction of C’s in a given sequence
(Jensen et al. 1999). It can range from 0(no C’s), to 1 (all C’s). For a sequence
that is 50% AT content, one would expect roughly 25% C’s.

(1999) 150:773-777
GC Skew
For many genomes there is a strand bias, such that one strand tends to have more
G’s, whilst the other strand has more C’s.This GC-skew bias can be measured the number
of G’s minus the number of C’s over a fixed length (e.g. 10,000 bp) of DNA(Jensen
et al. 1999). The values can range from +1 (all G’s on the examined sequence, with
all C’s on the other strand), to -1(the reverse case – all C’s on the examined sequence,
and all G’s on the other strand). There is a correlation with GC-skewand the replication
leading and lagging strands.

(1999) 150:773-777
Percent AT
The percent AT is a running average of the AT content, over a given window size.
Typically for a bacterial genomes of about5 Mbp, the window size is 10,000 bp. The
Percent AT can range from 0 (no AT content) to 1 (100% AT). The Percent AT iscorrelated
with other DNA structural features, such that AT rich regions are often more readily
melted, tend to be lessflexible and more rigid, although they can also be readily
compacted chromatin proteins (Pedersen et al. 2000).
* A.G. Pedersen and L.J. Jensen and H.H. Staerfeldt and S. Brunak and D.W. Ussery

AT Skew
For some genomes there is also an AT strand bias, such that one strand tends to have
more A’s, whilst the other strand hasmore T’s. This AT-skew bias is measured as the
number of A’s minus the number of T’s over a fixed length (e.g. 10,000 bp) ofDNA
(Jensen et al. 1999). The values can range from +1 (all A’s on the examined sequence,
with all T’s on the other strand), to-1 (the reverse case – all T’s on the examined
sequence, and all A’s on the other strand). For some genomes, there is acorrelation
with AT-skew and the replication leading and lagging strands.

Global Direct Repeats
Global Direct repeats are found by taking the first 100 bp of sequence, and
looking for the best match within the whole segment, on the same strand, in the
same direction [5′ to 3′] (Skovgaard et al. 2002). Values are binned into 10
values, and represent the lower end of the best match, and range from 0 (10% or
less match) to 9 (at least 90 out of the 100 nucleotides match perfectly).
Global Inverted Repeats
Global Direct repeats are found by taking the first 100 bp of sequence, and
looking for the best match within the whole segment, on the opposite strand, in
the same direction [5′ to 3′] (Skovgaard et al. 2002). Values are binned into
10 values, and represent the lower end of the best match and range from 0 (10%
or less match) to 9 (at least 90 out of the 100 nucleotides match perfectly).
