  • GO:0015293 Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported together in the same direction in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy.
  • GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
  • GO:0006835 The directed movement of dicarboxylic acids into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
  • GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
  • GO:0015138 Enables the transfer of fumarate from one side of a membrane to the other. Fumarate is a key intermediate in metabolism and is formed in the TCA cycle from succinate and converted into malate.
  • GO:0015366 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: malate(out) + H+(out) = malate(in) + H+(in).
  • GO:0015141 Enables the transfer of succinate, the dianion of ethane dicarboxylic acid, from one side of a membrane to the other.
  • GO:0070778 The directed movement of L-aspartate across a membrane by means of some agent such as a transporter or a pore.
