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.

== Function ==
 +
[https://www.uniprot.org/uniprot/MAP2_HUMAN MAP2_HUMAN] Cotranslationally removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). The catalytic activity of human METAP2 toward Met-Val peptides is consistently two orders of magnitude higher than that of METAP1, suggesting that it is responsible for processing proteins containing N-terminal Met-Val and Met-Thr sequences in vivo. Protects eukaryotic initiation factor EIF2S1 from translation-inhibiting phosphorylation by inhibitory kinases such as EIF2AK2/PKR and EIF2AK1/HCR. Plays a critical role in the regulation of protein synthesis.

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.
