Sialic acids are cytoprotectors, mainly localized on the surface of cell membranes with
multiple and outstanding cell biological functions. The history of their structural analysis …

The glycan chains of vertebrate glycoconjugates are composed mostly of five-and six-
carbon sugars. One striking exception is the family of sialic acids (Sia), which are R-keto …

Sialic acids are structurally unique nine-carbon keto sugars occupying the interface between
the host and commensal or pathogenic microorganisms. An important function of host sialic …

▪ Abstract Rhizobia are soil bacteria that can engage in a symbiosis with leguminous plants
that produces nitrogen-fixing root nodules. This symbiosis is based on specific recognition of …

Flagellins from three strains ofCampylobacter jejuni and one strain of Campylobacter coli
were shown to be extensively modified by glycosyl residues, imparting an approximate 6000 …

When the rhizosphere is nitrogen‐starved, legumes and rhizobia (soil bacteria) enter into a
symbiosis that enables the fixation of atmospheric dinitrogen. This implies a complex …

Abstract Soybean, Glycine max (L.) Merrill, is one of the most important food crops in the
world. High soybean yields require large amounts of N fertilizers, which are expensive and …

Sinorhizobium (Ensifer) fredii (S. fredii) is a rhizobial species exhibiting a remarkably broad
nodulation host-range. Thus, S. fredii is able to effectively nodulate dozens of different …

Ald-2-ulosonic acids are important components of natural glycoconjugates. Sialic acids,
namely N-and O-acyl derivatives of 5-amino-3, 5-dideoxy-D-glycero-D-galacto-non-2 …

The symbiotic diazotrophs comprise with a very diverse group of Gram negative soil
bacteria, collectively called as rhizobia found in nodule of legume plant. Rhizobia adopt …
