A general reaction scheme for glycosidase catalyzed hydrolyses, proceeding via a two-phase reaction, is presented. It explains, on the basis of some simple assumptions, transfer to nucleophiles other than water, selftransfer and substrateinhibition.

A thermostated diafiltration apparatus (1–2 ml) is described. A more rigorous control of cell-volume and temperature during equilibrium binding experiments by forced-flow ultrafiltration is obtained. Because the apparatus induces two reservoirs wit

D-Xylose isomerases from different bacterial strains were chemically modified with histidine and carboxylate-specific reagents. The active-site residues were identified by amino acid sequence analysis of peptides recognized by differential peptide ma

The influence of the chain length in n-alkyl β-D-xylopyranosides and of the para substituents in aryl β-D-xylopyranosides on the kinetic parameters (Ka, V) for hydrolysis of these substrates by a β-D-xylosidase from Penicillium wortmanni, has been

The binding of two activating cations, Co2+ and Mg2+, and of one inhibitory cation, Ca2+, to D-xylose isomerase from Streptomyces violaceoruber was investigated. Equilibrium-dialysis and spectrometric studies revealed that the enzyme binds 2 mol of C

D-Xylose isomerases from Streptomyces violaceoruber, Streptomyces sp., Lactobacillus xylosus, Lactobacillus brevis and Bacillus coagulans were rapidly inactivated by Woodward's reagent K. Second-order rate constants in the absence of ligands, at pH 6

The pH dependence of the kinetic parameters of beta-D-xylosidase (EC. 3.2.1.37) from Bacillus pumilus reveals that an acidic functional group with pK 8.0 is involved in the catalysis. The fast inactivation of the dimeric enzyme by near equivalent amo
