Rate-limiting Description

"The activity of uridine kinase (ATP: uridine 5'-phosphotransferase; EC, the rate-limiting enzyme of the UMP salvage pathway, was measured in human ovaries and ovarian carcinomas, in a spectrum of six rat hepatomas of different growth rates and in eleven normal rat tissues of high and low cell renewal rates."
