== Function == | |||
[https://www.uniprot.org/uniprot/MAP11_HUMAN MAP11_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). Required for normal progression through the cell cycle.[HAMAP-Rule:MF_03174]<ref>PMID:16274222</ref> <ref>PMID:17114291</ref> | |||

== Publication Abstract from PubMed == | |||
Methionine aminopeptidases (MetAPs) are an important class of enzymes that work co-translationally for the removal of initiator methionine. Chemical inhibition or gene knockdown is lethal to the microbes suggesting that they can be used as antibiotic targets. However, sequence and structural similarity between the microbial and host MetAPs has been a challenge in the identification of selective inhibitors. In this study, we have analyzed several thousands of MetAP sequences and established a pattern of variation in the S1 pocket of the enzyme. Based on this knowledge, we have designed a library of 17 azaindole based hydroxamic acid derivatives which selectively inhibited the MetAP from H. pylori compared to the human counterpart. Structural studies provided the molecular basis for the selectivity. | |||
