Crystal structure of 1,3Gal43A, an exo-β-1,3-galactanase from Clostridium thermocellum.
Glycoside hydrolase family 43 (GH43) consists of a variety of enzymes distributed widely in prokaryotes and eukaryotes. The mechanism by which GH43 enzymes hydrolyze oligosaccharides requires three essential acidic amino acid residues. However, one of them is thought to be missing in galactan β-1,3-galactosidases from the GH43 family. Ct1,3Gal43A, from Clostridium thermocellum, is comprised of ...
متن کاملKisspeptin-13 Improves Spatial Memory Consolidation and Retrieval against Amyloid-β Pathology
It has been shown that brain glucose metabolism impairment, obesity, and diabetes couldlead to cognitive decline and Alzheimer’s disease (AD) pathogenesis. Kisspeptin (KP) a G-proteincoupled receptor neuropeptide, has been suggested as a link between energy balance andreproduction. Some studies have shown that the attenuation of KP signaling decreases metabolismand energ...

متن کاملA Novel Method to Detect β-Cyclodextrin Glucosyl Transferase (β-CGTase) Activity on Polyacrylamide Gels
b-cyclodextrin glucosyl transferase (b-CGTase) hydrolyses starch to produce b-cyclodextrin by transglycosylation (cyclization) activity. The conventional method for detection of b-CGTase activity is based on detecting starch hydrolysis by iodine staining. This method reveals all amylolytic enzymes, but can not discriminate them. In the present study, we introduce a new method for specific detec...
متن کاملPectin biosynthesis: GALS1 in Arabidopsis thaliana is a β-1,4-galactan β-1,4-galactosyltransferase.
β-1,4-Galactans are abundant polysaccharides in plant cell walls, which are generally found as side chains of rhamnogalacturonan I. Rhamnogalacturonan I is a major component of pectin with a backbone of alternating rhamnose and galacturonic acid residues and side chains that include α-1,5-arabinans, β-1,4-galactans, and arabinogalactans. Many enzymes are required to synthesize pectin, but few h...
