Chain A   (Q3IUY6_RHOS4 | Q3IUY6)
molecular function
    GO:0008271    secondary active sulfate transmembrane transporter activity    Catalysis of the secondary active transfer of sulfate from one side of the membrane to the other. Secondary active transport is catalysis of the transfer of a solute from one side of a membrane to the other, up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by a chemiosmotic source of energy. Chemiosmotic sources of energy include uniport, symport or antiport.
    GO:0015116    sulfate transmembrane transporter activity    Enables the transfer of sulfate ions, SO4(2-), from one side of a membrane to the other.
biological process
    GO:1902358    sulfate transmembrane transport    The directed movement of sulfate across a membrane.
    GO:0008272    sulfate transport    The directed movement of sulfate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0055085    transmembrane transport    The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
cellular component
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
