FunFam 83: Selenocysteine lyase

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
Selenocysteine lyase. [EC: 4.4.1.16]
L-selenocysteine + reduced acceptor = selenide + L-alanine + acceptor.
  • Dithiothreitol or 2-mercaptoethanol can act as the reducing agent in the reaction.
  • The enzyme from animals does not act on cysteine, serine or chloroalanine, while the enzyme from bacteria shows activity with cysteine (cf. EC 2.8.1.7).
