Function
function
Reversibly transfers an adenylyl group from ATP to 4'-phosphopantetheine, yielding dephospho-CoA (dPCoA) and pyrophosphate.
Catalytic activity
- (R)-4'-phosphopantetheine + ATP + H+ = 3'-dephospho-CoA + diphosphate
Cofactor
Pathway
Cofactor biosynthesis; coenzyme A biosynthesis; CoA from (R)-pantothenate: step 4/5.
