  • Therefore, the characterization of the endo-1,4-beta-xylanase, encoded by um06350.1, is a further step towards the biotechnological application of U . maydis and its enzymes. (biomedcentral.com)
  • The systematic name of this enzyme class is chorismate pyruvate-lyase (4-hydroxybenzoate-forming). (wikipedia.org)
  • It belongs to the family of lyases, specifically the oxo-acid-lyases, which cleave carbon-carbon bonds. (wikipedia.org)
  • There are two types of RG lyases, which both cleave the alpha-1,4 bonds of the RG-I main chain (RG chain) through the beta-elimination reaction, but belong to two structurally unrelated polysaccharide lyase (PL) families, 4 and 11. (unl.edu)
  • The enzyme chorismate lyase (EC 4.1.3.40) catalyzes the first step in ubiquinone biosynthesis, the removal of pyruvate from chorismate, to yield 4-hydroxybenzoate in Escherichia coli and other Gram-negative bacteria. (wikipedia.org)
  • The systematic name of this enzyme class is chorismate pyruvate-lyase (4-hydroxybenzoate-forming). (wikipedia.org)
  • An enzyme that catalyzes the eliminative degradation of polysaccharides containing 1,4-beta-D-hexosaminyl and 1,3-beta-D-glucuronosyl or 1,3-alpha-L-iduronosyl linkages to disaccharides containing 4-deoxy-beta-D-gluc-4-enuronosyl groups. (lookformedical.com)
  • The rhamnogalacturonan lyase of the polysaccharide lyase family 4 (RGL4) is involved in the degradation of RG (rhamnogalacturonan) type-I, an important pectic plant cell wall polysaccharide, by cleaving the alpha-1,4 glycoside bond between L-rhamnose and D-galacturonic acids in the backbone of RG type-I through a beta-elimination reaction.

  • Three bacterial pectate lyases, a pectin lyase from Aspergillus niger, thestructures of rhamnogalacturonase A from Aspergillus aculeatus, RGase A,and the P22-phage tailspike protein, TSP, display the right-handedparallel beta-helix architecture first seen in pectate lyase. (embl.de)

  • This is the first structure of a polygalacturonase andcomprises a 10 turn right-handed parallel beta-helix domain with two loopregions forming a "tunnel like" substrate-binding cleft. (embl.de)
  • The functional similarity, that the enzymes all bindalpha-galactose containing polymers at an equivalent site involving PB1and its two flanking turn regions, further supports divergent evolution.We suggest that the stacking of the coils and the unusual nearperpendicular junction of PB2 and PB3 make the parallel beta-helix foldespecially likely to maintain similar main chain conformations duringdivergent evolution even after all vestige of similarity in primarystructure has vanished.
