  • deficient
  • A hexokinase preparation was obtained from aSaccharomyces cereviaiae mutant strain deficient in glucosephosphate isomerase (GPI) and mannosephosphate isomerase (MPI) by precipitation with ammonium sulfate. (naver.com)
  • Xylose
  • Xylose-isomerases are also commonly called fructose-isomerases due to their ability to interconvert glucose and fructose. (wikipedia.org)
  • The activity of D-xylose isomerase was first observed by Mitsuhashi and Lampen in 1953 in the bacterium Lactobacillus pentosus. (wikipedia.org)
  • In 1957, the D-xylose isomerase activity on D-glucose conversion to D-fructose was noted by Kooi and Marshall. (wikipedia.org)
  • Most pentoses and some hexoses are all substrates for D-xylose isomerase. (wikipedia.org)
  • An immobile xylose isomerase that was fixed on a solid surface was first developed in Japan by Takanashi. (wikipedia.org)
  • The tertiary structure was determined for several xylose isomerases from microbes starting in the mid 1980s (Streptomyces olivochromogenes in 1988, Streptomyces violaceoniger in 1988, Streptomyces rubiginosus in 1984, Arthrobacter B3728 in 1986, Actinoplanes missouriensis in 1992, and Clostridium thermosulfurogenes in 1990).

  • Hence D-xylose isomerase is used to produce these rare sugars which have very important applications in biology despite their low abundance. (wikipedia.org)
  • Xylose isomerase that can be isolated from red Chinese rice wine, which contains the bacterium Lactobacillus xylosus. (wikipedia.org)
  • Xylose isomerase in L. xylosus has a molecular weight of about 183000 Daltons. (wikipedia.org)
  • Thermal tests were also done by Kei Y. and Noritaka T. and the xylose isomerase was found to be thermally stable to about 60 degrees Celsius Xylose isomerase has a structure that is based on eight alpha/beta barrels that create an active site holding two divalent magnesium ions. (wikipedia.org)
  • fructose
  • Mannose-6 phosphate isomerase (MPI), alternately phosphomannose isomerase ( PMI ) (EC:5.3.1.8) is an enzyme which facilitates the interconversion of fructose 6-phosphate(F6P) and mannose -6-phosphate(M6P). (primidi.com)
  • inhibitors
  • The structure of rabbit muscle phosphoglucose isomerase complexed with various inhibitors shows that the enzyme is a dimer with two alpha/beta-sandwich domains in each subunit. (ebi.ac.uk)
  • Glycolysis
  • M6P can be converted to F6P by Mannose-6-Phosphate Isomerase and subsequently utilized in several metabolic pathways including Glycolysis and capsular polysaccharide biosynthesis. (primidi.com)
  • structure
  • Crystal structure of rabbit phosphoglucose isomerase, a glycolytic enzyme that moonlights as neuroleukin, autocrine motility factor, and differentiation mediator. (ebi.ac.uk)
  • Chalcone isomerase has a core 2-layer alpha/beta structure consisting of beta(3)-alpha(2)-beta-alpha(2)-beta(3). (wikipedia.org)
  • family
  • All thiol isomerases, of which now there are 21 in the PDI family, have evolved from an ancestral thioredoxin found in primitive unicellular organisms. (bloodjournal.org)
