Outline of Final Research Achievements |
Vibrio cholerae has more than 200 serogroups and remarkable genetic diversity. Our previous study revealed that V. cholerae has evolved by selecting either the M or LH gene at the locus MS6_A0927. We constructed deletion mutant strains of MS6_A0927 and hybrid strains, in which M and LH genes were exchanged. The strains with the M gene showed significant growth with methanethiol as the sole sulfur source. In addition, it was found that increase in methanethiol concentration delayed the lag-phase in a specific medium. The product of the M gene of V. cholerae may perform the function of O-acetyl-homoserine-sulfhydrylase, converting methanethiol to methionine.
