6.2.1.66

Accepted name:

glyine—[glycyl-carrier protein] ligase

Reaction:

ATP + glycine + holo-[glycyl-carrier protein] = AMP + diphosphate + glycyl-[glycyl-carrier protein] (overall reaction)
(1a) ATP + glycine = diphosphate + (glycyl)adenylate
(1b) (glycyl)adenylate + holo-[glycyl-carrier protein] = AMP + glycyl-[glycyl-carrier protein]

Other name(s):

dhbF (gene name); sfmB (gene name)

Systematic name:

glycine:[glycyl-carrier protein] ligase (AMP-forming)

Comments:

The adenylation domain of the enzyme catalyses the activation of glycine to (glycyl)adenylate, followed by the transfer of the activated compound to the free thiol of a phosphopantetheine arm of a peptidyl-carrier protein domain. The peptidyl-carrier protein domain may be part of the same protein (as in the case of DhbF in bacillibactin biosynthesis), or of a different protein. This activity is often found as part of a larger non-ribosomal peptide synthase.
