The enzymic synthesis of beta-[32P]UDP-N-acetylglucosamine.
Cells of Micrococcus sp. 2102 incorporate inorganic [32P]phosphate from the medium into the sugar-phosphate polymer of the wall. Controlled acid hydrolysis of sodium dodecyl sulphate-extracted cells gives N-acetylglucosamine 6-[32P]-phosphate which can be purified by ion-exchange chromatography and incubated with UTP in the presence of crude preparations of phosphoacetylglucosamine mutase from Neurospora crassa and UTP:N-acetylglucosamine 1-phosphate phosphotransferase from Bacillus licheniformis which act in concert to synthesise beta-[32P]UDP-N-acetylglucosamine.
