Phosphate permease

Phosphate permeases are membrane transport proteins that facilitate the diffusion of phosphate into and out of a cell or organelle. Some of these families include:
 * TC# 2.A.1.4 - Organophosphate:Pi Antiporter (OPA) Family, (i.e., Pho-84 of Neurospora crassa; TC# 2.A.1.9.2)
 * TC# 2.A.20 - Inorganic Phosphate Transporter (PiT) Family
 * TC# 2.A.47.2 - Phosphate porters of the Divalent Anion:Na+ Symporter (DASS) Family, includes Pho87/90/91
 * TC# 2.A.58 - Phosphate:Na+ Symporter (PNaS) Family
 * TC# 2.A.94 - Phosphate Permease (Pho1) Family
