Calcium Binding
catalytic Activity CATALYTIC ACTIVITY: Reaction=Release of an N-terminal amino acid, Xaa-|-Yaa- from a peptide, amide or arylamide. Xaa is preferably Ala, but may be most amino acids including Pro (slow action). When a terminal hydrophobic residue is followed by a prolyl residue, the two may be released as an intact Xaa-Pro dipeptide.; EC=3.4.11.2;
DNA Binding
EC Number 3.4.11.2
Enzyme Function FUNCTION: Metallopeptidase that binds to the auxin transport inhibitor N-1-naphthylphthalamic acid (NPA). Required for embryonic and seedling development as well as cell cycle progression. Homodimerization is required to proper localization and activity. May play a negative role in the regulation of PIN auxin transport proteins. {ECO:0000269|PubMed:11891249, ECO:0000269|PubMed:19531600, ECO:0000269|PubMed:20154099, ECO:0000269|PubMed:23065197}.
