Dala_Dala_lig_C

Dala_Dala_lig_C
PFAM accession number:PF07478
Interpro abstract (IPR011095):

This entry represents the C-terminal, catalytic domain of the D-alanine--D-alanine ligase enzyme EC 6.3.2.4. D-Alanine is one of the central molecules of the cross-linking step of peptidoglycan assembly. There are three enzymes involved in the D-alanine branch of peptidoglycan biosynthesis: the pyridoxal phosphate-dependent D-alanine racemase (Alr), the ATP-dependent D-alanine: D-alanine ligase (Ddl), and the ATP-dependent D-alanine:D-alanine-adding enzyme (MurF) [(PUBMED:12499203)].

GO function:D-alanine-D-alanine ligase activity (GO:0008716)

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Dala_Dala_lig_C
