| Summary: | Enterotoxigenic E. coli is an important zoonotic pathogen causing diarrhea in human and newborn animals. α - (1,2) fucosyltransferase 2 (FUT2) is closely associated with the formation of pathogenic receptors of Enterotoxigenic E. coli. Codon usage bias analysis can help to better understand the molecular mechanisms and evolutionary relationships of a particular gene. In order to understand the codon usage pattern of FUT2 gene, FUT2 gene coding sequences of nine species were selected from GenBank database for calculating the nucleotide composition (GC content) and genetic indexes including effective number of codons, relative synonymous codon usage and relative codon usage bias using R software, in order to analyze codon usage bias and base composition in FUT2 gene from different species. The results showed that the codon usage of FUT2 gene in different species was affected by GC bias, especially GC frequency of the third codon (GC3). Most of the optimal codons are biased towards the G/C-ending. GCC, CUG, UCC, GUG and AUC showed the highest relative synonymous codon usage value among different species, belonging to the most dominant codons. The usage characteristic of the FUT2 gene codon in Sus scrofa was similar to that of Bos taurus; Homo sapiens was similar to Pan troglodytes. The value of number of codons is significantly negatively correlated with GC3, and the relative higher frequency of optimal codon implied that FUT2 genes from different species had a strong bias in codon usage.
