AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
A novel reactive perstraction system has been developed based on liq.-core capsules, involving an enzyme-catalyzed reaction coupled with simultaneous in situ product recovery. Lipase-catalyzed reactions, hydrolysis of triprionin and nitrophenyl laurate, we ...
The pH-dependence of the reaction kinetics of lactase (b-galactosidase) [9031-11-2] from A. oryzae in different reaction media is presented in terms of a 2-parameter model. The lactase from A. oryzae seems to have replaced the A. niger lactase on the marke ...
The maximum concentration of alpha-cyclodextrin for the enzymatic degradation of starch is limited to about 13.5 g X 1(-1). By addition of decanol, the equilibrium of the reaction system can be shifted towards an alpha-cyclodextrin yield of 50% even at hig ...
Plasmodium falciparum is incapable of de novo purine biosynthesis, and is absolutely dependent on transporters to salvage purines from the environment. Only one low-affinity adenosine transporter has been characterized to date. In the present study we repo ...
The role of isocitrate lyase (ICL) in the glyoxylate cycle and its necessity for persistence and virulence of Mycobacterium tuberculosis has been well described. Recent reports have alluded to an additional role for this enzyme in M. tuberculosis metabolis ...
The development of a phasic system for the enzymic resoln. of racemic phenylalanine (I) up to benchtop pilot plant scale is described. The principle is based upon the hydrolysis of racemic Pr ester of I with immobilized a-chymotrypsin (II) in which only th ...
NAD(+) is a vital redox cofactor and a substrate required for activity of various enzyme families, including sirtuins and poly(ADP-ribose) polymerases. Supplementation with NAD(+) precursors, such as nicotinamide mononucleotide (NMN) or nicotinamide ribosi ...
Many hydrophilic organic compounds present at low concentrations in municipal wastewater, such as several pharmaceuticals, biocides and pesticides, are recalcitrant in conventional wastewater treatment plants. To improve the biodegradation of these compoun ...
Some nonenzymic epoxide-initiated polyolefin cyclisations are reported. The presented molecules are partially constrained analogues of (3S)-oxidosqualene, the natural substrate to many important cyclase enzymes. These model compounds feature a preformed C- ...
Poly(A) polymerase was purified 22,000-fold to homogeneity from a whole cell extract of Saccharomyces cerevisiae with a yield of 22%. The enzyme is a monomeric polypeptide with a denatured molecular weight of 63,000. Incorporation of labeled ATP into acid- ...
