Preparation and purification of substrate amounts of radioactive as well as non-radioactive dolichyl diphosphate N-acetylglucosamine and dolichyl diphosphate chitobiose made it possible to test and characterize tentatively the first three reactions of the dolichol pathway (enzyme I-III). The test conditions are described in detail. All three enzymes were solubilized from yeast membranes with detergents. Enzyme II and III were purified to give a purification factor of 35-fold and 70-fold, respectively. The reactions required divalent metal ions with an optimum concentration of 10 mM Mg2+. Enzyme II was stimulated almost to the same extent also by Ca2+. The Km values for UDP-N-acetylglucosamine for enzyme I and II were 15 and 10 muM, respectively, and for GDP-mannose (enzyme III) 7 muM. The apparent Km values for the lipophilic acceptor was 180 muM for enzyme I (dolichyl phosphate), 40 muM for enzyme II (dolichyl diphosphate N-acetylglucosamine) and 17 muM for enzyme III (dolichyl diphosphate chitobiose). The corresponding V values were approximately 1, 10, and 50 nmol X h-1 X mg protein-1. All reactions were inhibited by nucleoside diphosphates. << Less
