Enzyme reactions

• Enzyme class 2: Chain A: E.C.6.2.1.72 - L-serine--[L-seryl-carrier protein] ligase.
• Reaction: holo-[peptidyl-carrier protein] + L-serine + ATP = L-seryl-[peptidyl- carrier protein] + AMP + diphosphate

holo-[peptidyl-carrier protein] + L-serine + ATP (Bound ligand (Het Group name = BU9) matches with 44.44% similarity) = L-seryl-[peptidyl- carrier protein] + AMP + diphosphate

• Enzyme class 3: Chain A: E.C.6.3.2.14 - enterobactin synthase.
• Reaction: 3 2,3-dihydroxybenzoate + 3 L-serine + 6 ATP = enterobactin + 6 AMP + 6 diphosphate + 4 H⁺

3 × 2,3-dihydroxybenzoate (Bound ligand (Het Group name = BU9) matches with 54.55% similarity) + 3 × L-serine + 6 × ATP = enterobactin + 6 × AMP + 6 × diphosphate + 4 × H(+)

Note, where more than one E.C. class is given (as above), each may correspond to a different protein domain or, in the case of polyprotein precursors, to a different mature protein.
