[protein]-L-lysine [CPD:C02188];
small archaeal modifier protein
Comment
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 3.4.19.12, ubiquitinyl hydrolase 1. In peptidase family M67.
