| GO:0003674 | molecular_function | molecular_function | A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs. [GOC:pdt] |
| GO:0015199 | amino-acid betaine transmembrane transporter activity | molecular_function | Enables the transfer of betaine from one side of a membrane to the other. Betaine is the N-trimethyl derivative of an amino acid. [GOC:ai] |
| GO:0006811 | monoatomic ion transport | biological_process | The directed movement of a monoatomic ion into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Monatomic ions (also called simple ions) are ions consisting of exactly one atom. [GOC:ai] |
| GO:0006865 | amino acid transport | biological_process | The directed movement of amino acids, organic acids containing one or more amino substituents, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. [GOC:ai] |
| GO:0008150 | biological_process | biological_process | A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence. [GOC:pdt] |
| GO:0015838 | amino-acid betaine transport | biological_process | The directed movement of betaine, the N-trimethyl derivative of an amino acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. [GOC:ai] |
| GO:0055085 | transmembrane transport | biological_process | The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other. [GOC:dph, GOC:jid] |
| GO:0005575 | cellular_component | cellular_component | A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology |
| GO:0005886 | plasma membrane | cellular_component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
