small archaeal modifier protein
The enzyme, characterized from the archaeon Haloferax volcanii, specifically cleaves the ubiquitin-like small modifier proteins SAMP1 and SAMP2 from protein conjugates, hydrolysing the isopeptide bond between a lysine residue of the target protein and the C-terminal glycine of the modifier protein. The enzyme contains Zn2+. cf. EC 188.8.131.52, ubiquitinyl hydrolase 1. In peptidase family M67.
