Lipid carriers in the synthesis of high-mannose glycoproteins in algae

Particulate preparations from the chlorophyta Prototheca zopfii catalyze the incorporation of mannose and N-acetylglucosamine into glycolipids. These had been characterized as lipid monophosphate mannose, lipid pyrophosphate N,N′-diacetylchitobiose and various lipid-linked oligosaccharides containin...

These had been characterized as lipid monophosphate mannose, lipid pyrophosphate N,N′-diacetylchitobiose and various lipid-linked oligosaccharides containing two N-acetylglucosamine residues plus a variable number of mannose residues. The lipid moiety has the properties expected for dolichyl phosphate. The oligosaccharide-linked lipids serve as precursors for the formation of a polymer sensible to pronase digestion. The oligosaccharide is linked by N-glycosidic linkage to an asparagine residue. In longer incubation periods, a polymer insensitive to pronase hydrolysis, but precipitable by copper salts such as cell wall mannans is formed. Polymer formation is inhibited by 1 mM bacitracin. The reactions leading to the formation of the mannoprotein were found associated to the rough endoplasmic reticulum. The synthesis of mannans was found to occur in the Golgi vesicles. © 1979. 1979 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_03044165_v586_n3_p545_Romero http://hdl.handle.net/20.500.12110/paper_03044165_v586_n3_p545_Romero
