  • sugars
  • Simple sugars show promise as substrates for the formation of fuels and chemicals using heterogeneous catalysts in alcoholic solvents. (rsc.org)
  • Six of these transmembrane proteins mediate the metabolically relevant uptake of glucose, fructose and mannose for growth, two others catalyze the transport of only small amounts of these sugars, one protein is a galactose transporter but also able to transport glucose, two transporters act as glucose sensors, two others are involved in the pleiotropic drug resistance process, and the functions of the remaining hexose transporter-related proteins are not yet known.

  • C6 and C5 utilizing strains were used for simultaneous fermentation of hexose and pentose sugars of the pretreated sugarcane tops. (omicsonline.org)
  • When hexose sugars are the respiratory substrate, volume of CO 2 evolved equals volume of O 2 used and hence the value will be unity. (preservearticles.com)
  • phosphorolytic
  • ATP from phosphorolytic β-glucan cleavage minus ATP for substrate transport, mol ATP/mol hexose) from chemostats fed β-glucans with degree of polymerization (DP) 2-6 agreed well with the predicted value of ( n -1)/ n ( n = mean cellodextrin DP assimilated). (pnas.org)
  • complexes
  • We present the 2.8-Å crystal structures of GtfA complexes with vancomycin and the natural monoglycosylated peptide substrate, representing the first direct observation of acceptor substrate binding among closely related glycosyltransferases. (pnas.org)
  • respectively
  • The bidomain architecture of these enzymes, in which the N- and C-terminal domains appear to be independently responsible for the recognition and binding of the acceptor and donor substrates, respectively, suggests that the development of chimeric enzymes may be yet an additional approach to yield new antibiotic products. (pnas.org)
  • enzymes
  • Glycosylation of the aglycone core is performed in the final stages of biosynthesis by a series of structurally homologous, dedicated glycosyltransferase (Gtf) tailoring enzymes, using an NDP-hexose substrate as a sugar donor ( 1 ). (pnas.org)
  • Enzymes bind temporarily to one or more of the reactants - the substrate (s) - of the reaction they catalyze. (biology-pages.info)
  • All these enzymes contain one (or two in the case of types I to III isozymes) strongly conserved region which has been shown [ 6 ] to be involved in substrate binding. (expasy.org)
  • genetic
  • In this review, recent progress regarding the validation and development of the P. falciparum hexose transporter as a drug target is described, highlighting the importance of robust target validation through both chemical and genetic methods. (biomedcentral.com)
  • majority
  • The majority of methyl lactate is not formed from the substrate directly, but from methyl fructosides in a slow regime. (rsc.org)
  • source
  • They then switch to photoheterotrophic growth (with an organic substrate as carbon and electron source) or to photoautotrophic growth (if CO 2 and an inorganic electron donor such as hydrogen are supplied). (biomedcentral.com)

  • The molecular genetics of hexose transport in yeasts. (nih.gov)
  • However, the molecular genetics of hexose transport in many other yeasts remains to be established. (nih.gov)

  • Directed Divergent Evolution of a Thermostable D-Tagatose Epimerase towards Improved Activity for Two Hexose Substrates. (unibas.ch)
  • Research efforts nowadays are directed towards cheap sources of ethanol such as lignocellulosic substrates that are cost competitive and sustainable. (omicsonline.org)
