From: Analysis of codon usage bias of thioredoxin in apicomplexan protozoa
ENC-GC3 plot analysis in apicomplexan protozoa Trxs. The correlations between the effective number of codons (ENC) and the contents of the nucleotide G/C at the third codon location (GC3) were analyzed in apicomplexan protozoa Trxs, respectively. The standard curve represents the functional relationship between ENC and GC3 under mutation pressure rather than natural selection. X-axis represents GC3%, while Y-axis represents ENC. A Babesia spp., B Cryptosporidium spp., C Eimeria spp., D Plasmodium spp., E Theileria spp., F others (including Besnoitia besnoiti, Cyclospora cayetanensis, Gregarina niphandrodes, Hammondia hammondi, Neospora caninum, and Toxoplasma gondii)
