Abstract. In prostatic cytosol DHT1 is metabolized to 5α-androstane-3α (or β), 17α-diols with a half life of 2 h even at 4°C. Thus, [3H]DHT appears to be a poor marker for a quantitative assessment of androgen receptors (AR). Methyltrienolone (R1881) seems to be advantageous as it is not metabolized.

Abstract The effectiveness of nicotinamide and 5′-methyl nicotinamide as inhibitors of nuclear NAD nucleosidase and poly ADP-ribose polymerase from rat liver has been investigated. Nicotinamide inhibited the NAD nucleosidase and the poly ADP-ribose polymerase with Ki's of 5 · 10−4 M and 2 · 10−5 M, respectively, 5′-methyl nicotinamide with Ki's of 3 ...

Abstract Nicotinamide adenine dinucleotide nucleosidase (NAD glycohydrolase, EC 3.2.2.5) was demonstrated in venoms of various snakes. Among the venoms from 37 species of Viperidae, Crotalidae and Elapidae, venom of snakes in the genera Bungarus and Agkistrodon showed the highest activities.

Purification of streptococcal extracellular NAD+ nucleosidase is associated with changes of kinetic properties. A high-molecular weight component is required for a full activity of the enzyme. The component is not produced by bacteria and is present in the Todd-Hewitt cultivation medium, the beef-heart extract serving primarily as its source.

Structural and biochemical basis of NAD+ nucleosidase activity of TIR domain-containing proteins
2021NAD+ (nicotinamide adenine dinucleotide) was first identified as a cofactor in many redox reactions. Subsequently, it has been found to synchronize many cellular functions through the regulation of NAD+ consuming enzymes like CD38, sirtuins, and PARPs (poly ADP-ribose polymerases).

Preparative isoelectric focusing was used to separate free bacterial NAD+ nucleosidase from its complex with a bound host component. Both fractions were characterized by optimum temperature and activation energy of denaturation. The bacterial product is enzymically inactive. The enzymically active structure is formed upon binding to the host component.
