Protein

Cytosol aminopeptidase

Gene

pepA

Organism
Rickettsia prowazekii (strain Madrid E)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N-terminal amino acids from various peptides.

Catalytic activityi

Release of an N-terminal amino acid, Xaa-|-Yaa-, in which Xaa is preferably Leu, but may be other amino acids including Pro although not Arg or Lys, and Yaa may be Pro. Amino acid amides and methyl esters are also readily hydrolyzed, but rates on arylamides are exceedingly low.
Release of an N-terminal amino acid, preferentially leucine, but not glutamic or aspartic acids.

Cofactori
