NAD
|
D009243 |
[A coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH). (Dorland, 27th ed)

NAD+ Nucleosidase
|
D009244 |
[An enzyme that catalyzes the hydrolysis of nicotinamide adenine dinucleotide (NAD) to NICOTINAMIDE and ADENOSINE DIPHOSPHATE RIBOSE. Some are extracellular (ectoenzymes).The enzyme from some sources also catalyses the hydrolysis of nicotinamide adenine dinucleotide phosphate (NADP).

NADH Dehydrogenase
|
D009245 |
[A flavoprotein and iron sulfur-containing oxidoreductase that catalyzes the oxidation of NADH to NAD.

NADH, NADPH Oxidoreductases
|
D009247 |
[A group of oxidoreductases that act on NADH or NADPH. In general, enzymes using NADH or NADPH to reduce a substrate are classified according to the reverse reaction, in which NAD+ or NADP+ is formally regarded as an acceptor. This subclass includes only those enzymes in which some other redox carrier is the acceptor. (Enzyme Nomenclature, 1992, p100) EC 1.6.

NADP
|
D009249 |
[Nicotinamide adenine dinucleotide phosphate. A coenzyme composed of ribosylnicotinamide 5'-phosphate (NMN) coupled by pyrophosphate linkage to the 5'-phosphate adenosine 2',5'-bisphosphate. It serves as an electron carrier in a number of reactions, being alternately oxidized (NADP+) and reduced (NADPH). (Dorland, 27th ed)

NADP Transhydrogenase, AB-Specific
|
D061087 |
[A NADP transhydrogenase subtype found in certain types of BACTERIA and mammalian MITOCHONDRIA. This transhydrogenase uses a mechanism that can transfer hydrogen to either side, A or B, of the NAD(+) or NADP(+) ring structure. In heart mitochondria, the enzyme is A-specific with respect to NAD(+) and B-specific with respect to NADP(+).

NADP Transhydrogenases
|
D009250 |
[Enzymes that catalyze the reversible reduction of NAD by NADPH to yield NADP and NADH. This reaction permits the utilization of the reducing properties of NADPH by the respiratory chain and in the reverse direction it allows the reduction of NADP for biosynthetic purposes.
