Calcium Binding
catalytic Activity CATALYTIC ACTIVITY: Reaction=The enzyme shows specific recognition of a C-terminal tripeptide, Xaa-Yaa-Zaa, in which Xaa is preferably Ala or Leu, Yaa is preferably Ala or Tyr, and Zaa is preferably Ala, but then cleaves at a variable distance from the C-terminus. A typical cleavage is -Ala-Ala-|-Arg-Ala-Ala-Lys-Glu-Asn-Tyr-Ala-Leu-Ala-Ala.; EC=3.4.21.102;
DNA Binding
EC Number 3.4.21.102
Enzyme Function FUNCTION: Involved in the cleavage of a C-terminal peptide of 11 residues from the precursor form of penicillin-binding protein 3 (PBP3). May be involved in protection of the bacterium from thermal and osmotic stresses.
