Scattering on other regions of the molecule there were 10 single aminoacidsubstitutions, which could be explained as site-mutations of the gene.
此外，尚有10个氨基酸替代散在于分子内其它区域，这种替代是由于基因突变造成的。

The substitutions of aminoacid tended to gather around the putative antigen-binding sites.
氨基酸的替换趋于集中在假定的抗原结合位点附近。

DNA sequence revealed that 4-186 contains two aminoacidsubstitutions, K167R and S374C, both of which locate neither the substrate - binding sites nor the metal - binding sites of EAP.
