FunFam 8: Protein arginine N-methyltransferase 5

There are 1 EC terms in this cluster

Please note: EC 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.

Note: 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.

EC Term Annotations Evidence
Type II protein arginine methyltransferase. [EC: 2.1.1.320]
2 S-adenosyl-L-methionine + [protein]-L-arginine = 2 S-adenosyl-L- homocysteine + [protein]-N(omega),N(omega')-dimethyl-L-arginine.
  • The enzyme catalyzes the methylation of one of the terminal guanidino nitrogen atoms in arginine residues within proteins, forming monomethylarginine, followed by the methylation of the second terminal nitrogen atom to form a symmetrical dimethylarginine.
  • The mammalian enzyme is active in both the nucleus and the cytoplasm, and plays a role in the assembly of snRNP core particles by methylating certain small nuclear ribonucleoproteins.
  • Cf. EC 2.1.1.319, EC 2.1.1.321 and EC 2.1.1.322.
  • Formerly EC 2.1.1.23, EC 2.1.1.124, EC 2.1.1.125 and EC 2.1.1.126.
