ID 6.2.1.70 DE L-threonine--[L-threonyl-carrier protein] ligase. CA ATP + holo-[peptidyl-carrier protein] + L-threonine = AMP + diphosphate + CA L-threonyl-[peptidyl-carrier protein]. CC -!- The adenylation domain of the enzyme catalyzes the activation of CC L-threonine to (L-threonyl)adenylate, followed by the transfer of the CC activated compound to the free thiol of a phosphopantetheine arm of a CC peptidyl-carrier protein domain. CC -!- The peptidyl-carrier protein domain may be part of the same protein CC (as in the case of DhbF in bacillibactin biosynthesis), or of a CC different protein (as in the case of PmsD in pseudomonine CC biosynthesis). CC -!- This activity is often found as part of a larger non-ribosomal CC peptide synthase. DR P45745, DHBF_BACSU ; Q1IAL0, PMSD_PSEE4 ; Q52400, SYRB1_PSESY; //
