Methodological approach for the study of glycoconjugates inLeptolyngbyaVRUC 135

Abstract

In this paper we report the metabolism of hexosamines and the cellular compartmentalization of glycoconjugates in the cyanobacterium Leptolyngbya VRUC 135 by using D -[U-14 C]glucosamine as tracer. Glycoproteins as well as lipopolysaccharides were detected in the cell wall, membrane and buffer-soluble polymers. Evidence is also reported on the presence of lipopolysaccharides as released polymers. Abbreviation: RPs, released polymers
