HUMAN METHIONINE AMINOPEPTIDASE 2
Overview
The fungal metabolite fumagillin suppresses the formation of new blood, vessels, and a fumagillin analog is currently in clinical trials as an, anticancer agent. The molecular target of fumagillin is methionine, aminopeptidase-2 (MetAP-2). A 1.8 A resolution crystal structure of free, and inhibited human MetAP-2 shows a covalent bond formed between a, reactive epoxide of fumagillin and histidine-231 in the active site of, MetAP-2. Extensive hydrophobic and water-mediated polar interactions with, other parts of fumagillin provide additional affinity. Fumagillin-based, drugs inhibit MetAP-2 but not MetAP-1, and the three-dimensional structure, also indicates the likely determinants of this specificity. The structural, basis for fumagillin's potency and specificity forms the starting point, for structure-based drug design.
