Enzyme Commission Primary Name: aminopeptidase S

Enzyme Commission Synonyms: Mername-AA022 peptidase, SGAP, aminopeptidase (Streptomyces griseus), Streptomyces griseus aminopeptidase, S. griseus AP, double-zinc aminopeptidase

Taxonomic Range: Bacteria

Standard Gibbs Free Energy (ΔrG in kcal/mol): -48.12524Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Activated by Ca(2+). In the presence of Ca(2+), the best substrates are Leu-Phe, Leu-Ser, Leu-pNA (aminoacyl-p-nitroanilide), Phe-Phe-Phe and Phe-Phe. Peptides with proline in the P1' position are not substrates. Belongs to peptidase family M28.
