In enzymology, a bilirubin oxidase (EC 1.3.3.5) is an enzyme that catalyzes the chemical reaction 2 bilirubin + O2↔ 2 biliverdin + 2 H2O. Thus, the two substrates of this enzyme are bilirubin and O2, whereas its two products are biliverdin and H2O. This enzyme belongs to the ...
In enzymology, a NADPH dehydrogenase is an enzyme that catalyzes In enzymology, a NAD (P)H dehydrogenase (quinone) (EC 1.6.5.2) is an enzyme that catalyzes the chemical reaction NAD (P)H + H+ + a quinone↔ NAD (P)+ + a hydroquinone. The 4 substrates of this enzyme are NADH, ...
Superoxide dismutase (SOD) catalyzes the dismutation of superoxide radicals to hydrogen peroxide and molecular oxygen. SOD plays a critical role in the defense of cells against the toxic effects of oxygen radicals. SOD competes with nitric oxide (NO) for superoxide anion (which ...
The enzyme urate oxidase (UO), or uricase or factor-independent urate hydroxylase, absent in humans, catalyzes the oxidation of uric acid to 5-hydroxyisourate: Uric acid + O2 + H2O → 5-hydroxyisourate + H2O2 → allantoin + CO2 ...

Phospholipase C is an enzyme with system name phosphatidylcholine cholinephosphohydrolase. This enzyme catalyses the following chemical reaction: a phosphatidylcholine + H2O↔ 1, 2-diacyl-sn-glycerol + phosphocholine. The bacterial enzyme is a zinc protein. It also acts on ...
Glutamine synthetase (GS) (EC 6.3.1.2) is an enzyme that plays an essential role in the metabolism of nitrogen by catalyzing the condensation of glutamate and ammonia to form glutamine: Glutamate + ATP + NH3 → Glutamine + ADP + phosphate. Glutamine Synthetase uses ammonia ...
Glucose-6-phosphate dehydrogenase (G6PD or G6PDH) (EC 1.1.1.49) is an cytosolic enzyme that catalyzes the chemical reaction: D-glucose 6-phosphate + NADP+↔ 6-phospho-D-glucono-1, 5-lactone + NADPH + H+. This enzyme is in the pentose phosphate pathway (see image), a metabolic ...
