Question

Quizplus · Accepted Answer

The reaction of base + PRPP → nucleoside-5-phosphate + PP_i is catalyzed by phosphoribosyltransferases. These enzymes transfer the phosphoribosyl group from PRPP to the base, forming the corresponding nucleoside-5'-phosphate.

The Reaction, Base + PRPP → Nucleoside-5-Phosphate + PPi Is
