Crystal structure of Leucyl Aminopeptidase (pepA) from Xoo0834,Xanthomonas oryzae pv. oryzae KACC10331

Released:
Entry authors: Natarajan S, Huynh K-H, Kang LW

Function and Biology Details

Reactions catalysed:
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.
