Modular coenzyme specificity: a domain-swopped chimera of glutamate dehydrogenase.

30 Oct 2009 Domain-swopped chimeras of the glutamate dehydrogenases from Clostridium symbiosum (CsGDH) (NAD(+)-specific) and Escherichia coli (EcGDH) (NADP(+)-specific) have been produced, with the aim of testing the localization of determinants of coenzyme ... Read more...

The emerging characterization of lysine residue deacetylation on the modulation of mitochondrial function and cardiovascular biology.

21 Oct 2009 There is emerging recognition of a novel fuel and redox sensing regulatory program that controls cellular adaptation via nonhistone protein lysine residue acetyl posttranslation modifications. This program functions in tissues with high energy ... Read more...

Reconstitution of heterochromatin-dependent transcriptional gene silencing.

22 Sep 2009 Heterochromatin assembly in budding yeast requires the SIR complex, which contains the NAD-dependent deacetylase Sir2 and the Sir3 and Sir4 proteins. Sir3 binds to nucleosomes containing deacetylated histone H4 lysine 16 (H4K16) and, with Sir4, ... Read more...

Technical information about 'NAD'

Definition: 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)

Chemical name: Adenosine 5'-(trihydrogen diphosphate), P'-5'-ester with 3-(aminocarbonyl)-1-beta-D-ribofuranosylpyridinium, inner salt

Registry Number: 53-84-9

Descriptor UI: D009243
