FunFam 1: Ubiquinol oxidase

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 3 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
Alternative oxidase activity GO:0009916
Catalysis of the oxidation of ubiquinol by diverting electrons from the standard electron transfer chain, transferring them from ubiquinol to oxygen and generating water as the product.
4 O22048 (/ISS) O22049 (/ISS) O22049 (/ISS) O23913 (/ISS)
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).
1 Q07185 (/IPI)
Alternative oxidase activity GO:0009916
Catalysis of the oxidation of ubiquinol by diverting electrons from the standard electron transfer chain, transferring them from ubiquinol to oxygen and generating water as the product.
1 Q39219 (/IDA)

There are 4 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
Alternative respiration GO:0010230
Alternative respiration pathway consumes oxygen, oxidizes NADH to NAD+ and generates water. During electron flow, proton motive force is diminished resulting in fewer molecules of ATP compared to cytochrome pathway. The pathway is found in plants, algae and some protozoa.
2 O22049 (/ISS) O22049 (/ISS)
Response to cold GO:0009409
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 cold stimulus, a temperature stimulus below the optimal temperature for that organism.
1 Q39219 (/IMP)
Mitochondria-nucleus signaling pathway GO:0031930
A series of molecular signals that forms a pathway of communication from the mitochondria to the nucleus and initiates cellular changes in response to changes in mitochondrial function.
1 Q39219 (/IEP)
Cellular respiration GO:0045333
The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which either requires oxygen (aerobic respiration) or does not (anaerobic respiration).
1 Q39219 (/IDA)

There are 1 GO terms relating to "cellular component"

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
Mitochondrion GO:0005739
A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
