FunFam 6: Penicillin-binding protein 1B

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Serine-type D-Ala-D-Ala carboxypeptidase. [EC: 3.4.16.4]
Preferential cleavage: (Ac)(2)-L-Lys-D-Ala-|-D-Ala. Also transpeptidation of peptidyl-alanyl moieties that are N-acyl substituents of D-alanine.
  • A group of bacterial enzymes, membrane-bound.
  • Inhibited by beta-lactam antibiotics, which acylate the active site serine in the enzyme.
  • Distinct from EC 3.4.17.14.
  • Belongs to peptidase families S11, S12 and S13.

Peptidoglycan glycosyltransferase. [EC: 2.4.1.129]
(GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala))(n)- diphosphoundecaprenol + GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys- D-Ala-D-Ala)-diphosphoundecaprenol = (GlcNAc-(1->4)-Mur2Ac(oyl-L-Ala- gamma-D-Glu-L-Lys-D-Ala-D-Ala))(n+1)-diphosphoundecaprenol + undecaprenyl diphosphate.
  • The enzyme also works when the lysine residue is replaced by meso- 2,6-diaminoheptanedioate (meso-2,6-diaminopimelate, A2pm) combined with adjacent residues through its L-center, as it is in Gram- negative and some Gram-positive organisms.
  • The undecaprenol involved is ditrans,octacis-undecaprenol.
  • Involved in the synthesis of cell-wall peptidoglycan.
