• heparin
  • This enzyme catalyses the following chemical reaction beta-D-4-deoxy-Delta4-GlcAp-(1->3)-beta-D-GalNAc6S + H2O ⇌ {\displaystyle \rightleftharpoons } 5-dehydro-4-deoxy-D-glucuronate + N-acetyl-beta-D-galactosamine-6-O-sulfate The enzyme releases 4-deoxy-4,5-didehydro D-glucuronic acid or 4-deoxy-4,5-didehydro L-iduronic acid from chondroitin disaccharides, hyaluronan disaccharides and heparin disaccharides.

  • We observe a clear qualitative correlation between the antimicrobial activity of several β-defensins and related peptides and their gas-phase binding to a heparin -derived disaccharide ( HDD ). (rsc.org)
  • chitin
  • Chitin disaccharide deacetylase (EC 3.5.1.105, chitobiose amidohydolase, COD, chitin oligosaccharide deacetylase, chitin oligosaccharide amidohydolase) is an enzyme with systematic name 2-(acetylamino)-4-O-(2-(acetylamino)-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-D-glucopyranose acetylhydrolase.

  • yield
  • However, when excess donor was used, a previously unreported cysteine-bridged disaccharide was isolated in 54 % yield. (scielo.org.za)
  • The acetamido group on cysteine, which lowers the p K a of the carboxylic acid group of the amino acid, plays no role in the formation of the bridged disaccharide since 3-mercaptopropionic acid reacts in a similar manner to give the 3-mercaptopropionic acid-bridged disaccharide in 52 % yield.
