General annotation (Comments)

Function

Catalyzes the addition of meso-diaminopimelic acid to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanyl-D-glutamate (UMAG) in the biosynthesis of bacterial cell-wall peptidoglycan By similarity.

Catalytic activity

ATP + UDP-N-acetylmuramoyl-L-alanyl-D-glutamate + meso-2,6-diaminoheptanedioate = ADP + phosphate + UDP-N-acetylmuramoyl-L-alanyl-D-gamma-glutamyl-meso-2,6-diamino-heptanedioate. HAMAP MF_00208

Pathway

Cell wall biogenesis; peptidoglycan biosynthesis. HAMAP MF_00208

Subcellular location

Cytoplasm By similarity.

Post-translational modification

Carbamoylation is probably crucial for Mg2+ binding and, consequently, for the gamma-phosphate positioning of ATP By similarity.

Sequence similarities

Belongs to the murCDEF family. MurE subfamily.

Caution

Could be the product of a pseudogene.

Sequence caution

The sequence AE013218 differs from that shown. Reason: Frameshift at position 379. This is probably a pseudogene resulting from truncation by frameshift mutation, as it is possible that this bacterium does not produce peptidoglycan.
