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:

"
Type I PLP-dependent aspartate aminotransferase-like (Major domain)
".

FunFam 70: O-phosphoseryl-tRNA(Sec) selenium transferase

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
O-phospho-L-seryl-tRNA(Sec):L-selenocysteinyl-tRNA synthase. [EC: 2.9.1.2]
O-phospho-L-seryl-tRNA(Sec) + selenophosphate + H(2)O = L-selenocysteinyl-tRNA(Sec) + 2 phosphate.
  • In archaea and eukarya selenocysteine formation is achieved by a two- step process: EC 2.7.1.164 phosphorylates the endogenous L-seryl- tRNA(Sec) to O-phospho-L-seryl-tRNA(Sec), and then this misacylated amino acid-tRNA species is converted to L-selenocysteinyl-tRNA(Sec) by Sep-tRNA:Sec-tRNA synthase.
  • Formerly EC 2.9.1.n1.
