Protein names	Recommended name:     Glyceraldehyde-3-phosphate dehydrogenase B     EC=1.2.1.13 Alternative name(s):     NADP-dependent glyceraldehydephosphate dehydrogenase subunit B
Organism	Populus euphratica (Euphrates poplar)
Taxonomic identifier	75702 [NCBI]
Taxonomic lineage	Eukaryota › Viridiplantae › Streptophyta › Embryophyta › Tracheophyta › Spermatophyta › Magnoliophyta › eudicotyledons › core eudicotyledons › rosids › eurosids I › Malpighiales › Salicaceae › Saliceae › Populus

Protein attributes

Sequence length	10 AA.
Sequence status	Fragment.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Catalytic activity	D-glyceraldehyde 3-phosphate + phosphate + NADP(+) = 3-phospho-D-glyceroyl phosphate + NADPH.
Subunit structure	Tetramer of either four A chains (GAPDH 2) or two A and two B chains (GAPDH 1) By similarity.
Miscellaneous	Plants contain three forms of GAPDH: a cytosolic form which participates in glycolysis and two chloroplast forms which participates in photosynthesis. These three forms are encoded by distinct genes.
Sequence similarities	Belongs to the glyceraldehyde-3-phosphate dehydrogenase family.
