ACTIVE MUTANT (Q365->C) OF GLUCOSE 6-PHOSPHATE DEHYDROGENASE FROM LEUCONOSTOC MESENTEROIDES
Overview
The reduced coenzymes NADH and NADPH only differ by one phosphate, but in, the cell NADH provides reducing power for catabolism while NADPH is, utilized in biosynthetic pathways. Enzymes almost invariably discriminate, between the coenzymes, but glucose 6-phosphate dehydrogenase (G6PD) from, Leuconostoc mesenteroides is rare in being functionally dual specific. In, order to elucidate the coenzyme selectivity, the structures of NADP(+)-, and NAD(+)-complexed L. mesenteroides G6PD have been determined including, data to 2.2 and 2.5 A resolution, respectively, and compared with, unliganded G6PD crystallized in the same space groups. Coenzyme binding is, also compared with that in a ternary complex of a mutant in which Asp177, in the active site has been mutated to asparagine. There are no ... [(full description)]
