2k1g is a 1 chain structure with sequence from Escherichia coli K-12. This structure supersedes the now removed PDB entry 2jyx. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
MEPS_ECOLI A murein DD-endopeptidase with specificity for D-Ala-meso-diaminopimelic acid (mDAP) cross-links. Its role is probably to cleave D-Ala-mDAP cross-links to allow insertion of new glycans and thus cell wall expansion. Functionally redundant with MepM and MepH. Also has weak LD-carboxypeptidase activity on L-mDAP-D-Ala peptide bonds. Partially suppresses a prc disruption mutant.[1][2]
