Miscellaneousi

Miscellaneous

Plants contain three types of GAPDH: NAD-dependent cytosolic forms which participate in glycolysis, NAD-dependent chloroplastic forms which participate in plastidic glycolysis and NADP-dependent chloroplastic forms which participate in the photosynthetic reductive pentose phosphate pathway (Calvin-Benson cycle). All the 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.
