In enzymology, a carboxylate reductase (EC 1.2.99.6) is an enzyme that catalyzes the chemical reaction. an aldehyde + acceptor + H 2 O a carboxylate + reduced acceptor. The 3 substrates of this enzyme are aldehyde, acceptor, and H 2 O, whereas its two products are carboxylate and reduced acceptor.
Carboxylate ion Acrylate ion. In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion, an ion with negative charge. Carboxylate salts are salts that have the general formula M(RCOO) n, where M is a metal and n is 1, 2,....
In enzymology, a Delta1-piperideine-2-carboxylate reductase (EC 1.5.1.21) is an enzyme that catalyzes the chemical reaction L-pipecolate + NADP + ⇌ {\displaystyle \rightleftharpoons } Delta 1 -piperideine-2-carboxylate + NADPH + H +
The 3 substrates of this enzyme are L-proline, NAD +, and NADP +, whereas its 4 products are 1-pyrroline-2-carboxylate, NADH, NADPH, and H +. This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-NH group of donors with NAD+ or NADP+ as acceptor.
The enzyme aminocyclopropane-1-carboxylic acid synthase (ACC synthase, ACS) (EC 4.4.1.14) catalyzes the synthesis of 1-Aminocyclopropane-1-carboxylic acid (ACC), a precursor for ethylene, from S-Adenosyl methionine (AdoMet, SAM), an intermediate in the Yang cycle and activated methyl cycle and a useful molecule for methyl transfer:
Thus, the two substrates of this enzyme are (1R,6R)-1,6-dihydroxycyclohexa-2,4-diene-1-carboxylate and NAD +, whereas its 4 products are catechol, CO 2, NADH, and H +. This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor.
The reaction it catalyzes is: pyruvate + HCO − 3 + ATP → oxaloacetate + ADP + P. It is an important anaplerotic reaction that creates oxaloacetate from pyruvate. PC contains a biotin prosthetic group [1] and is typically localized to the mitochondria in eukaryotes with exceptions to some fungal species such as Aspergillus nidulans which have a cytosolic PC.
The three substrates of this enzyme are (S)-1-pyrroline-5-carboxylate, NAD +, and H 2 O, whereas its three products are glutamate, NADH, and H +. This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-NH group of donors with NAD+ or NADP+ as acceptor.
