Polysaccharide lyases [PDF]

FEMS Microbiology Reviews, 1995
Polysaccharide lyases are the products of various microorganisms, bacteriophage and some eukaryotes. All such enzymes cleave a hexose-1,4-alpha- or beta-uronic acid sequence by beta-elimination. They are in some examples, the only known type of enzymes degrading their polyanionic substrates.

Wheat Cell Wall Polysaccharides (Dietary Fibre)

, 2020
Wheat is a major source of dietary fibre in the human diet, with whole grain containing about 11–15% fibre/g dry wt. However, in most countries wheat is most widely consumed after milling to give white flour, reducing the fibre content to less than 5 ...

Regulating polysaccharide structure and bioactivity via free radical degradation: a review of mechanisms, effects, and application prospects

Frontiers in Nutrition
Natural polysaccharides from food sources (e.g., ginseng, seaweed, apricot, larch) have diverse bioactivities (antioxidant, immunomodulatory, hypoglycemic) that are closely related to human nutritional health, but their structural heterogeneity (e.g ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
