UDP-glucose:glycoprotein glucosyltransferase

1448 amino acids

Selectively reglucosylates unfolded glycoproteins, thus providing quality control for protein transport out of the ER. Unfolded, denatured glycoproteins are substantially better substrates for glucosylation by this enzyme than are the corresponding native proteins. This protein and transient glucosylation may be involved in monitoring and/or assisting the folding and assembly of newly made glycoproteins, in order to identify glycoproteins that need assistance in folding from chaperones.

Belongs to the glycosyltransferase 8 family.

GPT1

Glucose-6-phosphate/phosphate translocator 1, chloroplastic

388 amino acids

Glucose 6-phosphate (Glc6P) transporter. Transports also inorganic phosphate, 3-phosphoglycerate, triose phosphates and, to a leser extent, phosphoenolpyruvate. Responsible for the transport of Glc6P into plastids of heterotrophic tissues where it can be used as a carbon source for starch biosynthesis, as substrate for fatty acid biosynthesis or as substrate for NADPH generation via the oxidative pentose phosphate pathway (OPPP). Required for pollen maturation and embryo sac development.

Belongs to the TPT transporter family. GPT (TC 2.A.7.9) subfamily.
