The key role of catechol oxidase in enzymatic browning makes it a common target for inhibition. While a number of inhibitory strategies exist such as high temperature treatments(70-90 °C) to eliminate catechol oxidase catalytic activity, [6] a popular strategy is decreasing the pH with citric acid. Catechol oxidase is more catalytically active ...
Trivial name Catechol: Resorcinol: Hydroquinone: IUPAC name benzene-1,2-diol benzene-1,3-diol benzene-1,4-diol Other names pyrocatechol 1,2-dihydroxybenzene o-dihydroxybenzene o-benzenediol resorcin 1,3-dihydroxybenzene m-dihydroxybenzene m-benzenediol 1,4-dihydroxybenzene p-dihydroxybenzene p-benzenediol Structure
Although rarely encountered, the officially "preferred IUPAC name" (PIN) of catechol is benzene-1,2-diol. [23] The trivial name pyrocatechol is a retained IUPAC name, according to the 1993 Recommendations for the Nomenclature of Organic Chemistry. [24] [25]
Chemical nomenclature is a set of rules to generate systematic names for chemical compounds.The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC).
Thus, the two substrates of this enzyme are catechol and O 2, whereas its two products are [[dibenzo[1,4]dioxin-2,3-dione]] and H 2 O. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. The systematic name of this enzyme class is catechol:oxygen oxidoreductase ...
Hemocyanin is homologous to the phenol oxidases (e.g. tyrosinase) since both proteins have histidine residues, called "type 3" copper-binding coordination centers, as do the enzymes tyrosinase and catechol oxidase. [19] In both cases inactive precursors to the enzymes (also called zymogens or proenzymes) must be activated first. This is done by ...
Catechol 2,3-dioxygenase (EC 1.13.11.2, 2,3-pyrocatechase, ... pyrocatechol 2,3-dioxygenase) is an enzyme with systematic name catechol:oxygen 2,3-oxidoreductase ...
Figure 1. The overall reaction of catechol 1,2-dioxygenase. Using a non-heme iron(III) complex, 1,2-CTD is able to oxidatively cleave catechol into cis,cis-muconic acid. More specifically, 1,2-CTD is an intradiol dioxygenase, a family of catechol dioxygenases that cleaves the bond between the phenolic hydroxyl groups of catechol using an Fe 3 ...
