Hydroxycyclohexanecarboxylate dehydrogenase
Encyclopedia
In enzymology, a hydroxycyclohexanecarboxylate dehydrogenase is an enzyme
that catalyzes
the chemical reaction
-3,4-dihydroxycyclohexane-1-carboxylate + NAD+
(1S,4S)-4-hydroxy-3-oxocyclohexane-1-carboxylate + NADH + H+
Thus, the two substrates
of this enzyme are (1S,3R,4S)-3,4-dihydroxycyclohexane-1-carboxylate and NAD+
, whereas its 3 products
are (1S,4S)-4-hydroxy-3-oxocyclohexane-1-carboxylate, NADH
, and H+
.
This enzyme belongs to the family of oxidoreductase
s, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (1S,3R,4S)-3,4-dihydroxycyclohexane-1-carboxylate:NAD+ 3-oxidoreductase. Other names in common use include dihydroxycyclohexanecarboxylate dehydrogenase, and (-)t-3,t-4-dihydroxycyclohexane-c-1-carboxylate-NAD+ oxidoreductase.
Enzyme
Enzymes are proteins that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates...

Catalysis
Catalysis is the change in rate of a chemical reaction due to the participation of a substance called a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. A catalyst may participate in multiple chemical transformations....

Chemical reaction
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, typically following the input of some type of energy, such as heat, light or electricity...

Substrate (biochemistry)
In biochemistry, a substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate. In the case of a single substrate, the substrate binds with the enzyme active site, and an enzyme-substrate complex is formed. The substrate is transformed into one or...

Nicotinamide adenine dinucleotide
Nicotinamide adenine dinucleotide, abbreviated NAD, is a coenzyme found in all living cells. The compound is a dinucleotide, since it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine base and the other nicotinamide.In metabolism, NAD is involved...

Product (chemistry)
Product are formed during chemical reactions as reagents are consumed. Products have lower energy than the reagents and are produced during the reaction according to the second law of thermodynamics. The released energy comes from changes in chemical bonds between atoms in reagent molecules and...
