For the published genome sequence, the G+C content (GC%) is
about 38.3%. Or more precisely:
Length of sequence is 12069303 bp:
Nucleotide count:
A = 3729537
T = 3717515
C = 2313352
G = 2308899
GC% = 0.382975802330922
If you consider coding and non-coding regions separately:
For ORFs...
Length of combined ORF sequences is 17210970 bp:
Nucleotide count:
A = 5603270
T = 4779634
C = 3289938
G = 3538128
GC% = 0.396727552253011
For non-coding regions...
Length of combined non-coding sequences is 3085113 bp:
Nucleotide count:
A = 1004675
T = 1004448
C = 538077
G = 537913
GC% = 0.348768424365655
Here non-coding regions are taken to be any sequence which isn't
in an ORF, Ty element, LTR sequence, or RNA sequence.
Hope this helps.
