Enzyme Information

3.4.11.10
Bacterial leucyl aminopeptidase.
based on mapping to UniProt O25294
Release of an N-terminal amino acid, preferentially leucine, but not glutamic or aspartic acids.
-!- Similar aminopeptidases were isolated from Escherichia coli and Staphylococcus thermophilus. -!- Belongs to peptidase families M17 and M28.
3.4.11.1
Leucyl aminopeptidase.
based on mapping to UniProt O25294
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.
-!- Is activated by heavy metal ions. -!- Belongs to peptidase family M17. -!- Formerly EC 3.4.1.1.
