Functional Annotations
Enzyme classification and Gene Ontology terms linked to this protein.
Gene Ontology (GO)
2- GO:0008933 Catalysis of the cleavage of a peptidoglycan chain into a peptidoglycan chain with N-acetyl-1,6-anhydromuramyl-[peptide] at the reducing end + a peptidoglycan chain with N-acetylglucosamine at the non-reducing end. Includes endolytic transglycosylase activity that fragments the glycan chain internally and exolytic transgylcosylase activity that cleaves a terminal disaccharide from the end of the glycan strand.
- GO:0009253 The chemical reactions and pathways resulting in the breakdown of peptidoglycans, any of a class of glycoconjugates found in bacterial cell walls and consisting of long glycan strands of alternating residues of beta-(1,4) linked N-acetylglucosamine and N-acetylmuramic acid, cross-linked by short peptides.

Ligand evidence
Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.
Highest-confidence structural evidence: ligands co-crystallized with this exact protein. If the source PDB is loaded in TPW, use Open crystal to inspect it in the structure viewer.
No PDB structure with a co-crystallized ligand found for this exact protein.
Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
