UniProtKB accession:  P9WGT7

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Functions in inorganic phosphate uptake, is probably the main carrier for phosphate uptake, it is the most highly expressed of the 3 PstS proteins under phosphate starvation (PubMed:20933472). Binds phosphate; probably able to bind both H(2)PO(4)(-) and HPO(4)(2-) (PubMed:24615888). Part of the ABC transporter complex PstSACB involved in phosphate import (Probable). Probably plays a role in host phagosome maturation arrest (PubMed:20844580).
