| Abstract: | The Effects of precursor amino acids and necessary cofactors(Mg 2+) on engineering enzyme production of glutathione was investigated.Aimed to search the best enzymatic condition,several different concentrations of precursor amino acid(L-glutamic acid,L-cysteine and glycine) and necessary cofactors(Mg 2+) were tested on the ability of production of glutathione by enzymatic synthesis of recombinant E.coli.The experimental results showed that when the concentration of L-glutamic acid,glycine and L-cysteine was... |
