Protein
Sodium-dependent phosphate transport protein 1, chloroplastic
Organism
Arabidopsis thaliana
Function
Specific for inorganic phosphate transport across the thylakoid membrane in a sodium dependent manner. Binds glutamate but cannot transport it. May act as an ascorbate transporter at the thylakoid membrane (Probable).
Similarity
Belongs to the major facilitator superfamily. Sodium/anion cotransporter (TC 2.A.1.14) family.
