Abstract
An enzyme (lincosaminide O-nucleotidyltransferase) that catalyzes 3-(5'-ribonucleotidylation) of pirlimycin and several other lincosaminide antibodies has been purified approximately 35-fold from cell-free extracts of Streptomyces coelicolor Müller NRRL 3532 (UC 5240). The crude enzyme was prepared using lysozyme and was treated with MnCl2 and (NH4)2SO4. Final purification was achieved by anion exchange chromatography. The pirlimycin reaction product was verified as being pirlimycin-3-(5'-adenylate) by NMR spectroscopy and MS. As a result of purification, this lincosaminide nucleotidylating and inactivating enzyme was separated from the macrolide phosphorylating enzyme also present in the cell-free extract.Entities:
