Protein attributes

Sequence length	249 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Removes the amino-terminal methionine from nascent proteins.
Catalytic activity	Release of N-terminal amino acids, preferentially methionine, from peptides and arylamides.
