E.COLI FOLC IN COMPLEX WITH DHPP AND ADP
Overview
In some bacteria, such as Escherichia coli, the addition of L-glutamate to, dihydropteroate (dihydrofolate synthetase activity) and the subsequent, additions of L-glutamate to tetrahydrofolate (folylpolyglutamate, synthetase (FPGS) activity) are catalyzed by the same enzyme, FolC. The, crystal structure of E. coli FolC is described in this paper. It showed, strong similarities to that of the FPGS enzyme of Lactobacillus casei, within the ATP binding site and the catalytic site, as do all other, members of the Mur synthethase superfamily. FolC structure revealed an, unexpected dihydropteroate binding site very different from the folate, site identified previously in the FPGS structure. The relevance of this, site is exemplified by the presence of phosphorylated dihydropteroate, a, reaction ... [(full description)]
