Function

[AMPM2_HUMAN] Removes the N-terminal methionine from nascent proteins. 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.^[1] ^[2] ^[3] ^[4] 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.^[5] ^[6] ^[7] ^[8]

Publication Abstract from PubMed

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.
