Regulation of dolichyl phosphate-linked oligosaccharide assembly has been studied during the course of diethylstilbestrol-induced chick oviduct differentiation. Oviduct membranes from treated chicks form 4.6 times as much GlcNAc-P-P-Dol and GlcNAc2-P-P-Dol upon incubation with UDP-[14C]GlcNAc and MgCl2 than do membranes from untreated chicks. Assembly of oligosaccharide-lipid was studied by incubation of membranes with purified exogenous [14C]GlcNAc2-P-P-Dol and GDP-Man. Man transfer required a divalent cation (10 mM Mg2+) and detergent (0.5% Nonidet P-40 is optimal) and occurs in the presence of amphomycin (500 micrograms/ml). The apparent Km for GDP-Man is 1 microM and for [14C]GlcNAc2-P-P-Dol is 0.45 microM. The products are a series of sequentially formed dolichyl pyrophosphate-linked saccharides up to Man5GlcNAc2, the first of which is Man beta 1,4GlcNAc2. The same products are formed either in the presence or absence of amphomycin. Conversion of GlcNAc2-P-P-Dol to higher oligosaccharides is stimulated 3-fold by estrogen treatment of chicks. Similarly, the conversion of partially purified exogenously added Man beta-[14C]GlcNAc2-P-P-Dol is 4.6-fold higher after diethylstilbestrol treatment.
