CC -!- FUNCTION: Alpha-N-methyltransferase that methylates the N-terminus of
CC target proteins containing the N-terminal motif [Ala/Pro/Ser]-Pro-Lys
CC when the initiator Met is cleaved. Specifically catalyzes mono-, di- or
CC tri-methylation of exposed alpha-amino group of Ala or Ser residue in
CC the [Ala/Ser]-Pro-Lys motif and mono- or di-methylation of Pro in the
CC Pro-Pro-Lys motif (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=N-terminal L-alanyl-L-prolyl-L-lysyl-[protein] + 3 S-adenosyl-
CC L-methionine = 3 H(+) + N-terminal N,N,N-trimethyl-L-alanyl-L-prolyl-
CC L-lysyl-[protein] + 3 S-adenosyl-L-homocysteine;
