CATH Classification

Domain Context

CATH Clusters

Superfamily Type I PLP-dependent aspartate aminotransferase-like (Major domain)
Functional Family Selenocysteine lyase

Enzyme Information

4.4.1.16
Selenocysteine lyase.
based on mapping to UniProt Q68FT9
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).
