It is the fact that three methionines distributed in the Hsp16.3 will begradually oxidated, in vitro, by hydrogen peroxide(H2O2). When the hsp16. 3 gene was cloned with pMV261 plasmid vector and transfected into Mycobacterium smegmatis, we found that the ability of anti-H2O2 will be decreased greatly among the strains of M. smeg. containing pMV261-hspl6. 3 while compared with the control strains of M. smeg. containing free plasmid vector. But we found that the ability of anti-H2O2 will be increased greatly among the strains of M. smeg. containing pMV261-38kDa while compared with the same control.
