Bovine Ubiquitin carboxyl-terminal hydrolase isozyme L1,UCHL1 ELI

Ubiquitin-protein hydrolase involved both in the processing of ubiquitin precursors and of ubiquitinated proteins.

This enzyme is a thiol protease that recognizes and hydrolyzes a peptide bond at the C-terminal glycine of ubiquitin (By similarity).

Also binds to free monoubiquitin and may prevent its degradation in lysosomes (By similarity).

The homodimer may have ATP-independent ubiquitin ligase activity (By similarity).
