Alginate lyases that degrade alginate via a β-elimination reaction fall into seven polysaccharide lyase (PL) families. Although the structures and catalytic mechanisms of in other PL families have been clarified, those family PL6 yet to be revealed. Here, crystal structure AlyGC, from marine bacterium Glaciecola chathamensis S18K6T, was solved, its mechanism illustrated. AlyGC is homodimeric enzyme adopts distinct lyases. Each monomer contains N-terminal domain functionally unknown...
Marine bacteria play important roles in the degradation and cycling of algal polysaccharides. However, dynamics epiphytic bacterial communities their polysaccharide during kelp decay are still unclear. Here, we performed metagenomic analyses to investigate identities predicted metabolic abilities early late stages
Marine bacterial alginate lyases play a role in marine degradation and carbon cycling. Although large number of have been characterized, reports on with special characteristics are still rather less. Here, gene alyPM encoding an lyase polysaccharide family 7 (PL7) was cloned from Pseudoalteromonas sp. SM0524 expressed Escherichia coli. AlyPM shows 41% sequence identity to characterized lyases, indicating that is new PL7 enzyme. The optimal pH for activity 8.5. showed the highest at 30°C...
Alginate lyases play important roles in alginate degradation the ocean. Although a large number of have been characterized, little is yet known about those extremely cold polar environments, which may unique mechanisms for environmental adaptation and degradation. Here, we report characterization novel PL7 lyase AlyC3 from
Alginate oligosaccharides (AOS) have many biological activities and significant applications in prebiotics, nutritional supplements, plant growth development. lyases unique advantages the preparation of AOS. However, only a limited number alginate been so far reported to potentials AOS with specific degrees polymerization. Here, an alginate-degrading strain Pseudoalteromonasarctica M9 was isolated from Sargassum, five were predicted its genome. These putative expressed their degradation...
Abstract The molecular structure of starches isolated from five jackfruits (M2, M3, M4, M8 and X1) its relationship with physicochemical properties were investigated. Although they had uniform amylose (AM) content, the jackfruit displayed different properties, including their pasting, thermal, crystal texture properties. Furthermore, differences in (i.e., average weight-average molar mass (Mw) amylopectin (AP) as well same AP fine structure) also found starches. results indicated that starch...
Cordyceps sinensis is one of the most valuable medicinal fungi in Orient. It naturally distributed eastern extension area Qinghai-Tibet plateau, at an altitude over 4000 m high. In order to investigate genetic variation and evolutionary relationships C. from different geographical regions, 17 isolates were collected provinces complete sequences rDNA ITS determined. On basis 5.8S region analysis, it was clearly shown that within are highly homologous regardless origin. The distance values...
A polysaccharide from jackfruit pulp (JFP-Ps) has been found to exhibit various types of bioactivities. This study aimed investigate the effects and potential mechanisms JFP-Ps on non-alcoholic fatty liver disease (NAFLD) induced by high-fat diet in rats. The pathological changes function were determined using hematoxylin-eosin staining biochemical analysis. RT-qPCR Western blots employed expression proteins associated with lipid metabolism proinflammatory cytokines. Results showed that...
Abstract Background Alginate oligosaccharides (AOs) are the degradation products of alginate, a natural polysaccharide abundant in brown algae. AOs generated by enzymatic hydrolysis have diverse bioactivities and show broad application potentials. production via enzymolysis is now generally with sodium alginate as raw material, which chemically extracted from In contrast, direct algae more advantageous on account its cost reduction eco-friendly. However, there been only few attempts reported...
