查询词典 control vector

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.

尽管Hsp16.3中有三个甲硫氨酸在体外能被过氧化氢(H_2O_2)逐一氧化，我们将Hsp16.3基因克隆到pMV261质粒上，并转染到耻垢分枝杆菌中发现，转染了pMV261-16.3的耻垢分枝杆菌抗过氧化氢的能力大大下降，而对照含pMV261-38kDa的耻垢分枝杆菌抗过氧化氢的能力却有明显的增强，据此，我们认为，Hsp16.3在细胞内可能不具有抗过氧化氢的能力。
