Crystal structure of engineered Bradyrhizobium japonicum glycine:[carrier protein] ligase complexed with carrier protein from Agrobacterium tumefaciens and ATP
Template:ABSTRACT PUBMED 23541895
Function
[AACL1_BRAJA] Catalyzes the ATP-dependent activation of L-glycine and its transfer to the phosphopantetheine prosthetic group covalently attached to the vicinal carrier protein bsr0959 of yet unknown function. May participate in nonribosomal peptide synthesis or related processes. L-alanine is a poor substrate whereas L-serine or D-amino acids are not substrates for ATP-dependent activation. Does not display tRNA aminoacylation activity. [AACP_AGRT5] Aminoacyl carrier protein. Can be charged with L-alanine, L-glycine or L-serine, via the formation of a thioester bond between the amino acid and the 4'-phosphopantetheinyl prosthetic group, catalyzed by the Atu2573 ligase.
