==HUMAN GLYOXALASE I WITH BENZYL-GLUTATHIONE INHIBITOR==
-
The zinc metalloenzyme glyoxalase I catalyses the glutathione-dependent, inactivation of toxic methylglyoxal. The structure of the dimeric human, enzyme in complex with S-benzyl-glutathione has been determined by, multiple isomorphous replacement (MIR) and refined at 2.2 A resolution., Each monomer consists of two domains. Despite only low sequence homology, between them, these domains are structurally equivalent and appear to have, arisen by a gene duplication. On the other hand, there is no structural, homology to the 'glutathione binding domain' found in other, glutathione-linked proteins. 3D domain swapping of the N- and C-terminal, domains has resulted in the active site being situated in the dimer, interface, with the inhibitor and essential zinc ion interacting with side, chains ...
