Function
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). Plays only a minor role in N-terminal methionine removal. Less efficient when the second residue is Val, Gly, Cys or Thr.
