AFLATOXIN ALDEHYDE REDUCTASE (AKR7A1) FROM RAT LIVER
OverviewOverview
The structure of the rat liver aflatoxin dialdehyde reductase (AKR7A1) has, been solved to 1.38-A resolution. Although it shares a similar, alpha/beta-barrel structure with other members of the aldo-keto reductase, superfamily, AKR7A1 is the first dimeric member to be crystallized. The, crystal structure also reveals details of the ternary complex as one, subunit of the dimer contains NADP(+) and the inhibitor citrate. Although, the underlying catalytic mechanism appears similar to other aldo-keto, reductases, the substrate-binding pocket contains several charged amino, acids (Arg-231 and Arg-327) that distinguish it from previously, characterized aldo-keto reductases with respect to size and charge. These, differences account for the substrate specificity for 4-carbon, acid-aldehydes ... [(full description)]
