Overview

Basic information about this protein and its source genome.

Accession: KP13_20275

Amino acids: 558
Structure source: AlphaFold + ColabFold

GO:0006812 The directed movement of a monoatomic cation, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Monatomic cations (also called simple cations) are positively charged ions consisting of exactly one atom. GO:0015297 Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. The reaction is: solute A(out) + solute B(in) = solute A(in) + solute B(out). GO:0008324 Enables the transfer of cation from one side of a membrane to the other. GO:1902600 The directed movement of a proton across a membrane. GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0006813 The directed movement of potassium ions (K+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
