Non-phosphorylating NADP-dependent glyceraldehyde-3-phosphate dehydrogenase (GAPDH) (EC 1.2.1.9) from spinach leaves was purified to homogeneity using an improved purification procedure. Thus, a major contaminant with molecular mass and ion-exchange properties similar to non-phosphorylating GAPDH was eliminated. Using this pure non-phosphorylating GAPDH, cofactor stereospecificity was determined by 1H NMR. Analysis of the NADPH formed from the hydride transfer from glyceraldehyde-3-phosphate to [4-2H]NADP showed that the enzyme belongs to the A-stereospecific dehydrogenase family. This stereospecificity is the same as that described for the aldehyde dehydrogenase (ALDH) superfamily and opposite to that of the phosphorylating GAPDH. Moreover, results from peptide sequencing analysis suggest a similarity in sequence between the non-phosphorylating GAPDH and ALDHs. Thus, the results taken all together strongly suggest that non-phosphorylating GAPDH belongs to the ALDH family and has no close relationship to the phosphorylating GAPDH class.

D009249 NADP 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).

D010766 Phosphorylation The introduction of a phosphoryl group into a compound through the formation of an ester bond between the compound and a phosphorus moiety. Phosphorylations
D010944 Plants Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE. Plant
