-!- FUNCTION: Catalyzes DD-carboxypeptidase and transpeptidation reactions. -!- CATALYTIC ACTIVITY: Preferential cleavage: (Ac)(2)-L-Lys-D-Ala-|- D-Ala. Also transpeptidation of peptidyl-alanyl moieties that are N-acyl substituents of D-alanine. -!- ENZYME REGULATION: Inhibited by cephaloridine. -!- BIOPHYSICOCHEMICAL PROPERTIES: Kinetic parameters: KM=400 uM for N(alpha)-acetyl-L-Lys-D-Ala-D-thiolactate; KM=470 uM for benzoyl-Gly-thiogylcolate; KM=380 uM for benzoyl-D-Ala-thiogylcolate; pH dependence: Optimum pH is 12; -!- SUBCELLULAR LOCATION: Secreted (Probable). Note=May be anchored in the membrane via a C-terminal amphiphatic alpha helix. -!- DEVELOPMENTAL STAGE: Expression starts at the end of the exponential phase and peaks two hours into sporulation. There is no enzyme activity in spores. -!- INDUCTION: Expression is sigma H-dependent. -!- SIMILARITY: Belongs to the peptidase S13 family. ----------------------------------------------------------------------- Copyrighted by the UniProt Consortium, see http://www.uniprot.org/terms Distributed under the Creative Commons Attribution-NoDerivs License ----------------------------------------------------------------------- |
