Marine Polysaccharide Sulfatases

Marine Polysaccharide Sulfatases

Polysaccharides are the most abundant and the most complex organic molecules in the ocean. In contrast to land polysaccharides, many marine polysaccharides are highly sulfated; in particular, the cell walls of macroalgae harbor a high diversity of sulfated polysaccharides (carrageenans, agarans, fucoidans, ulvans, etc.). These sulfated polysaccharides, biosynthesized by macroalgal primary produ...

CrosstalkSulfotransferases and Sulfatases in Mycobacteria

environment is to modulate binding interactions between proteins and glycoconjugates [6, 7]. In contrast to the large number of sulfotransferases eukaryotic systems into the domain of Prokarya. Rhizo-bia are nitrogen-fixing bacteria that enter into a symbi-Berkeley, California 94720 otic relationship with a variety of legumes. The sulfotran-sferases, NodH and NoeE, catalyze the sulfation of sec...

Marine Polysaccharide Networks and Diatoms at the Nanometric Scale

Despite many advances in research on photosynthetic carbon fixation in marine diatoms, the biophysical and biochemical mechanisms of extracellular polysaccharide production remain significant challenges to be resolved at the molecular scale in order to proceed toward an understanding of their functions at the cellular level, as well as their interactions and fate in the ocean. This review cover...

Pseudoalteromonas arabiensis sp. nov., a marine polysaccharide-producing bacterium

A novel exopolysaccharide-producing bacterium, designated strain k53(T), was isolated from sediment from the Arabia Sea, Indian Ocean. The strain was Gram-negative, motile, strictly aerobic, oxidase-positive and catalase-positive, and required Na(+) for growth. Its major isoprenoid quinone was ubiquinone-8 (Q-8), and its cellular fatty acid profile mainly consisted of C16 : 1ω7c, C16 : 0 and C1...
