Some NAD is converted into the coenzyme nicotinamide adenine dinucleotide phosphate (NADP), whose chemistry largely parallels that of NAD, though its predominant role is as a coenzyme in anabolic metabolism. In the name NAD +, the superscripted plus sign indicates the positive formal charge on one of its nitrogen atoms. A biological coenzyme ...
This category groups enzymes that use nicotinamide adenine dinucleotide (NAD + and its reduced form, NADH) in redox reactions. See also Category:NADPH-dependent enzymes.. In general, the NAD is not stably associated with the enzyme, being a coenzyme; hence, we call such enzymes "NADH-dependent" enzymes, rather than simply "NADH enzymes".
NAD + kinase (EC 2.7.1.23, NADK) is an enzyme that converts nicotinamide adenine dinucleotide (NAD +) into NADP + through phosphorylating the NAD + coenzyme. [6] NADP + is an essential coenzyme that is reduced to NADPH primarily by the pentose phosphate pathway to provide reducing power in biosynthetic processes such as fatty acid biosynthesis and nucleotide synthesis.

Adenosylhomocysteinase (EC 3.13.2.1, S-adenosylhomocysteine synthase, S-adenosylhomocysteine hydrolase, adenosylhomocysteine hydrolase, S-adenosylhomocysteinase, SAHase, AdoHcyase) is an enzyme that catalyzes the nicotinamide adenine dinucleotide (NAD +) dependent, reversible hydrolysis of S-adenosylhomocysteine to homocysteine and adenosine.
