FunFam 4386: GTP cyclohydrolase 1

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 4 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
Tetrahydrobiopterin biosynthetic process GO:0006729
The chemical reactions and pathways resulting in the formation of tetrahydrobiopterin, the reduced form of biopterin (2-amino-4-hydroxy-6-(1,2-dihydroxypropyl)-pteridine). It functions as a hydroxylation coenzyme, e.g. in the conversion of phenylalanine to tyrosine.
1 Q94465 (/IDA)
Response to oxidative stress GO:0006979
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 oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals.
1 Q94465 (/IDA)
Regulation of G-protein coupled receptor protein signaling pathway GO:0008277
Any process that modulates the frequency, rate or extent of G-protein coupled receptor protein signaling pathway activity.
1 Q94465 (/IDA)
Folic acid-containing compound biosynthetic process GO:0009396
The chemical reactions and pathways resulting in the formation of folic acid and its derivatives.
1 P51601 (/IMP)
Folic acid-containing compound biosynthetic process GO:0009396
The chemical reactions and pathways resulting in the formation of folic acid and its derivatives.
1 O13774 (/ISO)
Folic acid biosynthetic process GO:0046656
The chemical reactions and pathways resulting in the formation of folic acid, pteroylglutamic acid.

There are 6 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
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
1 O13774 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 Q94465 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 O13774 (/ISO)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 O13774 (/IDA)
Membrane GO:0016020
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
1 Q94465 (/IDA)
Phagocytic vesicle GO:0045335
A membrane-bounded intracellular vesicle that arises from the ingestion of particulate material by phagocytosis.
