Enzymes are Highly Specific Enzymes are highly specific both in the reaction catalyzed and in their choice of reactants, which are called substrates. An enzyme usually catalyzes a single chemical reaction or a set of closely related reactions. The degree of specificity for substrate is usually ...

Discovering cryptic natural products by substrate manipulation Cryptic halogenation reactions result in natural products with diverse structural motifs and bioactivities. However, these halogenated species are difficult to detect with current analytical methods because the final products are often not halogenate...
N-type ATP pyrophosphatases (SCOPe c.26.2.1) are a versatile family of enzymes involved in amino acid and nucleic acid metabolism [67,68,69]. The catalytic core consists of a five-strand parallel β-sheet flanked by α-helices, which catalyzes substrate adenylation and coupling to ammonia (...
Such spatial congruence is supplemented by Finite difference Poisson Boltzmann analysis which filters out electrostatically unfavorable configurations. The congruent configurations are used to compute an index (BrassIndex), which reflects the broad substrate profile of the active site. We identify an acetyl...
The synergistic action of accessory enzymes enhances the hydrolytic potential of a cellulase mixture but is highly substrate specific N. The synergistic action of accessory enzymes enhances the hydrolytic potential of a "cellulase mixture" but is highly substrate specific. Biotechnology for... JG,...
technically, adouble sugar, since it is composed of two molecules of thesimple sugarglucosebonded together. The digestive enzymemaltasecatalyzes a reaction in which a molecule of water is inserted at the point at which the two glucose units are linked, thereby disconnecting them, as illustrated ...
substrate. However, we only considered small molecules included among the experimentally confirmed enzyme-substrate pairs in our dataset. Among such a limited and biased subset, enzymes are quite specific catalysts, and therefore most of the potential secondary substrates are not included for the ...
The tandem biocatalytic reaction in multi-shelled ZIF-8 MOFs was then investigated using glucose as the substrate. The aerobic oxidation of glucose in the presence of GOx produces gluconic acid and H2O2, H2O2 then acts as an oxidizing substrate for HPR which catalyzes the oxidation of o-phenylene...
