Protein attributes

Sequence length	444 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Cell wall formation. Catalyzes the addition of glutamate to the nucleotide precursor UDP-N-acetylmuramoyl-L-alanine (UMA) By similarity. HAMAP MF_00639
Catalytic activity	ATP + UDP-N-acetylmuramoyl-L-alanine + glutamate = ADP + phosphate + UDP-N-acetylmuramoyl-L-alanyl-D-glutamate. HAMAP MF_00639
Pathway	Cell wall biogenesis; peptidoglycan biosynthesis. HAMAP MF_00639
Subcellular location	Cytoplasm By similarity HAMAP MF_00639.
Sequence similarities	Belongs to the MurCDEF family.
Sequence caution	The sequence AAO78556.1 differs from that shown. Reason: Erroneous initiation.
