| Abstract: | Somanase locates in the cytosol of Escherichia coli JM105. The transformation of the expression plasmid pWM513 containing parathionase gene of Flavobacterium sp.failed to contribute to the somanase activity of JM105. It suggested that soman was not degradated by parathionase. E. coli UM255, a catalase gene deficient strain, was found to have its endogeneous somanase activity. The transformation of E. coli UM255 with expression plasmid pAMKatE6 bearing the catalase gene of E. coli did not exhibit any influence on somanase level. It implies that somanase activity in E. coli is not the function of catalase and these enzymes are encoded by different genes. |
