Function
Methionine aminopeptidase 1 (MetAP1) is an enzyme that removes the N-terminal methionine from nascent proteins during translation. This process is often observed when the second amino acid in the protein sequence is small and uncharged (such as Ala, Cys, Gly, Pro, Ser, Thr, or Val). MetAP1 is essential for normal cell cycle progression.
