Function

function

Catalyzes two sequential steps in the biosynthesis of coenzyme A. In the first step cysteine is conjugated to 4'-phosphopantothenate to form 4-phosphopantothenoylcysteine. In the second step the latter compound is decarboxylated to form 4'-phosphopantotheine.

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.

Catalytic activity
