An analysis of the codon usage of Pasteurella haemolytica A1

Analysis of approximately 17 kbp of nucleotide sequences from three different regions of the genome of Pasteurella haemolytica A1 showed that the mol% G+C of P. haemolytica A1 DNA is 38.5%. When only the coding sequences (approx. 10 kbp) were analysed, a similar value of 38.8% was obtained. A comparison of the relative synonymous codon usage values of the cloned genes showed that P. haemolytica A1 has a very different codon usage pattern from that of Escherichia coli.
