Analysis of codon usage for ATCC 43037 (left panel) and BU063 (right panel). The continuous curves indicate the NC values to be expected for a given GC3s content in the absence of other factors shaping codon usage. Every dot represents a protein coding gene, dots not positioned near the curve therefore represent genes that display a considerable codon usage bias. GC3s: G + C content at synonymous positions, NC: effective number of codons used within the sequence of a gene
