FunFam 15861: O-methyltransferase 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 5 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
Lignin biosynthetic process GO:0009809
The chemical reactions and pathways resulting in the formation of lignins, a class of polymers formed by the dehydrogenetive radical polymerization of various phenylpropanoid monomers.
1 Q9FK25 (/IMP)
Flavonol biosynthetic process GO:0051555
The chemical reactions and pathways resulting in the formation of flavonols, a member of a class of vascular pigments formed by consecutive oxidative processes from the flavonoid intermediates flavanones and dihydroflavonols. Flavonols are the most widespread of the flavonoids and have a wide array of physiological activities.

There are 4 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 Q9FK25 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 Q9FK25 (/IDA)
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
1 Q9FK25 (/IDA)
Plasmodesma GO:0009506
A fine cytoplasmic channel, found in all higher plants, that connects the cytoplasm of one cell to that of an adjacent cell.
