NADP sodium salt 화학적 특성, 용도, 생산

• 개요

  The nicotinamide adenine dinucleotide phosphate oxidase（NADP）is a multicomponent system that transfers an electron to molecular oxygen by way of FAD and heme to form superoxide (O2?) .Cytochrome b558 is a membrane-bound heterodimer lodged in the wall of the secondary granules; the large glycosylated β subunit is gp91phox and the small nonglycosylated α subunit is p22phox.The cytoplasmic tail of gp91phox binds FAD, heme, and NADPH, which are required for electron transfer to oxygen (O2).Neutrophil stimulation leads to aggregation and phosphorylation of p47phox, p67phox, p40phox, and the small guanosine triphosphate (GTP)–binding proteins RAC1/RAC2, which dock with the cytochrome at the membrane through binding of p47phox and p22phox.

• 화학적 성질

  White to slightly yellowish powder

• 용도

  β-Nicotinamide adenine dinucleotide 2′-phosphate (NADP+) and β-Nicotinamide adenine dinucleotide 2′-phosphate, reduced (NADPH) comprise a coenzyme redox pair (NADP+:NADPH) involved in a wide range of enzyme catalyzed oxidation reduction reactions.
  β-Nicotinamide Adenine Dinucleotide Phosphate Sodium Salt Hydrate is a substrate NADP which plays a role in a variety of metabolic processes.

• Biosynthesis

  In general, NADP+ is synthesized before NADPH is. Such a reaction usually starts with NAD+ from either the de-novo or the salvage pathway, with NAD+ kinase adding the extra phosphate group. ADP-ribosyl cyclase allows for synthesis from nicotinamide in the salvage pathway, and NADP+ phosphatase can convert NADPH back to NADH to maintain a balance.Some forms of the NAD+ kinase, notably the one in mitochondria, can also accept NADH to turn it directly into NADPH.[3][4] The prokaryotic pathway is less well understood, but with all the similar proteins the process should work in a similar way.

• Biochem/physiol Actions

  Electron acceptor

• Mechanism of action

  NADP sodium salt exerts its effect by competitively inhibiting nucleotide metabolism through the suppression of enzymes like nucleoside diphosphate kinase (NDPK) and adenosine kinase (ADK). Additionally, it serves as a substrate for enzymes like DNA polymerases and RNA polymerases, enabling the integration of NADP monosodium salt into nucleic acids during replication and transcription.
