The glucosyltransferase which catalyzes the conversion of GlcNAc-PP-undecaprenol into Glc(beta 1----4)GlcNAc-PP-undecaprenol in the presence of UDP-glucose was solubilized from Bacillus coagulans AHU 1366 membranes by treatment with 0.1% Triton X-100 and partially purified by means of column chromatography on Sephacryl S-300 and DEAE-Sephacel. The final preparation was virtually free from other enzymes involved in the de novo synthesis of teichoic acid. The enzyme had a pH optimum of 6.6-8.0 and a Km value for UDP-glucose of 21 microM. The enzyme required 40 mM MgCl2, 0.6 M KCl, and 0.1% Nonidet P-40 for full activity.
