GDP-L-Galactose Phosphorylase is a novel protein involved in ascorbate biosynthesis, which was shown to catalyze the transfer of GMP from GDP-galactose to a variety of hexose-1-phosphate acceptors.
PDS3 is phytoene desaturase (phytoene dehydrogenase), an enzyme that catalyzes the desaturation of phytoene to zeta-carotene during carotenoid biosynthesis.
FDM4 belongs to a subgroup of SGS3-like proteins that act redundantly in RNA-directed DNA methylation: AT1G15910 (FDM1), AT4G00380 (FDM2), AT3G12550 (FDM3), AT1G13790 (FDM4), AT1G80790 (FDM5).
CR88, ATHSP90.5, ATHSP90C, EMB1956, EMBRYO DEFECTIVE 1956, HEAT SHOCK PROTEIN 88.1, HEAT SHOCK PROTEIN 90.5, HSP88.1, HSP90.5, HSP90C
Background:
CR88 is a chloroplast-targeted 90-kDa heat shock protein located in the stroma involved in red-light mediated deetiolation response and crucial for protein import into the chloroplast stroma.
T-protein is the aminomethyltransferase of the glycine cleavage multienzyme system (GCS), also known as the glycine decarboxylase complex, and essential for photorespiration and one-carbon metabolism.
PEX6 is an apparent ATPase similar to yeast and human protein required for peroxisomal biogenesis. It may facilitate recycling of PEX5, the peroxisomal matrix protein receptor, and thereby promote peroxisomal matrix protein import.
