|
2',3'-Cyclic-Nucleotide Phosphodiesterases
|
D015087 |
[Nucleoside-2',3'-cyclic phosphate nucleotidohydrolase. Enzymes that catalyze the hydrolysis of the 2'- or 3'- phosphate bonds of 2',3'-cyclic nucleotides. Also hydrolyzes nucleoside monophosphates. Includes EC 3.1.4.16 and EC 3.1.4.37. EC 3.1.4.-.

2',5'-Oligoadenylate Synthetase
|
D015088 |
[An enzyme that catalyzes the conversion of ATP into a series of (2'-5') linked oligoadenylates and pyrophosphate in the presence of double-stranded RNA. These oligonucleotides activate an endoribonuclease (RNase L) which cleaves single-stranded RNA. Interferons can act as inducers of these reactions.

|
2,3-Diphosphoglycerate
|
D019794 |
[A highly anionic organic phosphate which is present in human red blood cells at about the same molar ratio as hemoglobin. It binds to deoxyhemoglobin but not the oxygenated form, therefore diminishing the oxygen affinity of hemoglobin. This is essential in enabling hemoglobin to unload oxygen in tissue capillaries. It is also an intermediate in the conversion of 3-phosphoglycerate to 2-phosphoglycerate by phosphoglycerate mutase (EC 5.4.2.1). (From Stryer Biochemistry, 4th ed, p160; Enzyme Nomenclature, 1992, p508)

2,4,5-Trichlorophenoxyacetic Acid
|
D015085 |
[An herbicide with strong irritant properties. Use of this compound on rice fields, orchards, sugarcane, rangeland, and other noncrop sites was terminated by the EPA in 1985. (From Merck Index, 11th ed)

|
2,4-Dichlorophenoxyacetic Acid
|
D015084 |
[An herbicide with irritant effects on the eye and the gastrointestinal system.

|
2,4-Dinitrophenol
|
D019297 |
[A toxic dye, chemically related to trinitrophenol (picric acid), used in biochemical studies of oxidative processes where it uncouples oxidative phosphorylation. It is also used as a metabolic stimulant. (Stedman, 26th ed)

|
2,5-Dimethoxy-4-Methylamphetamine
|
D004290 |
[A psychedelic phenyl isopropylamine derivative, commonly called DOM, whose mood-altering effects and mechanism of action may be similar to those of LSD.

2,6-Dichloroindophenol
|
D015086 |
[A dye used as a reagent in the determination of vitamin C.

|
2-Acetolactate Mutase
|
D015072 |
[An enzyme involved in the biosynthesis of isoleucine and valine. It converts 2-acetolactate into 3-hydroxy-2-oxo-isovalerate. Also acts on 2-hydroxy-2-acetobutyrate to form 2-hydroxy-2-oxo-3-methylvalerate. EC 5.4.99.3.

|
2-Acetylaminofluorene
|
D015073 |
[A hepatic carcinogen whose mechanism of activation involves N-hydroxylation to the aryl hydroxamic acid followed by enzymatic sulfonation to sulfoxyfluorenylacetamide. It is used to study the carcinogenicity and mutagenicity of aromatic amines.
] |
|
2-Amino-5-phosphonovalerate
|
D015763 |
[The D-enantiomer is a potent and specific antagonist of NMDA glutamate receptors (RECEPTORS, N-METHYL-D-ASPARTATE). The L form is inactive at NMDA receptors but may affect the AP4 (2-amino-4-phosphonobutyrate; APB) excitatory amino acid receptors.
