Interactioni

Subunit structurei

Homotetramer. Component of a complex that contains two dimers of PRK, two tetramers of GAPDH and CP12. CP12 associates with GAPDH, causing its conformation to change. This GAPDH/CP12 complex binds PRK to form a half-complex (one unit). This unit probably dimerizes due partially to interactions between the enzymes of each unit.1 Publication

Miscellaneousi

Miscellaneous

GAPDHB, the second subunit found in plants, is absent in algae.
Algae contain three forms of GAPDH: two cytosolic forms which participate in glycolysis and one chloroplastic form which participates in photosynthesis. These three forms are encoded by distinct genes.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
