Pseudaminic acid cytidylyltransferase

Pseudaminic acid cytidylyltransferase (EC 2.7.7.81, PseF) is an enzyme with systematic name CTP:5,7-diacetamido-3,5,7,9-tetradeoxy-L-glycero-alpha-L-manno-nonulosonic acid cytidylyltransferase. This enzyme catalyses the following chemical reaction

CTP + 5,7-bis(acetylamino)-3,5,7,9-tetradeoxy-L-glycero-alpha-L-manno-2-nonulopyranosonic acid ⇌ diphosphate + CMP-5,7-bis(acetylamino)-3,5,7,9-tetradeoxy-L-glycero-alpha-L-manno-2-nonulopyranosonic acid

Mg²⁺ is required for activity.
