The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:

"
ATP synthase, F0 complex, subunit A

FunFam 4: ATP synthase subunit a

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 2 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
2 P00846 (/IPI) P00846 (/IPI)
Transmembrane transporter activity GO:0022857
Enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other.

There are 6 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Aging GO:0007568
A developmental process that is a deterioration and loss of function over time. Aging includes loss of functions such as resistance to disease, homeostasis, and fertility, as well as wear and tear. Aging includes cellular senescence, but is more inclusive. May precede death and may succeed developmental maturation (GO:0021700).
3 P05504 (/IEP) P05504 (/IEP) P05504 (/IEP)
Response to hyperoxia GO:0055093
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating increased oxygen tension.
3 P05504 (/IEP) P05504 (/IEP) P05504 (/IEP)
ATP biosynthetic process GO:0006754
The chemical reactions and pathways resulting in the formation of ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
2 P00846 (/TAS) P00846 (/TAS)
Cristae formation GO:0042407
The assembly of cristae, the inwards folds of the inner mitochondrial membrane.
2 P00846 (/TAS) P00846 (/TAS)
Mitochondrial ATP synthesis coupled proton transport GO:0042776
The transport of protons across a mitochondrial membrane to generate an electrochemical gradient (proton-motive force) that powers ATP synthesis.
2 P00846 (/IC) P00846 (/IC)
Mitochondrial ATP synthesis coupled proton transport GO:0042776
The transport of protons across a mitochondrial membrane to generate an electrochemical gradient (proton-motive force) that powers ATP synthesis.
2 P00846 (/TAS) P00846 (/TAS)
