Accepted name: D-alanine—poly(phosphoribitol) ligase
Reaction: ATP + D-alanine + poly(ribitol phosphate) = AMP + diphosphate + O-D-alanyl-poly(ribitol phosphate)
Other name(s): D-alanyl-poly(phosphoribitol) synthetase; D-alanine: membrane acceptor ligase; D-alanine-D-alanyl carrier protein ligase; D-alanine-membrane acceptor ligase; D-alanine-activating enzyme
Systematic name: D-alanine:poly(phosphoribitol) ligase (AMP-forming)
Comments: A thioester bond is formed transiently between D-alanine and the sulfhydryl group of the 4′-phosphopantetheine prosthetic group of D-alanyl carrier protein during the activation of the alanine. Involved in the synthesis of teichoic acids.
