Enzyme Information

3.4.11.5

Prolyl aminopeptidase.

based on mapping to UniProt P96084

Release of N-terminal proline from a peptide.

-!- Present in the cytosol of mammalian and microbial cells. -!- In contrast to the mammalian form, the bacterial form of the enzyme hydrolyzes both polyproline and prolyl-2-naphthylamide. -!- The mammalian enzyme, which is not specific for prolyl bonds, is possibly identical with EC 3.4.11.1. -!- Belongs to peptidase family S33. -!- Formerly EC 3.4.1.4.
