The ubiquitin-like small archaeal modifer protein 2 (SAMP2) is involved in sulfur transfer during molybdenum cofactor biosynthesis. SAMP2 has been demonstrated to form covalent conjugates with substrate proteins through an isopeptide linkage via C-terminal di-glycine motif in a streamlined archaeal E1-dependent pathway. SAMP2 also forms homo-conjugates through the intermolecular isopeptide bond between the C-terminal glycine and the Lys58 side chain, a feature that likely resembles polyubiquitination. This protein adopt a typical ubiquitin-like fold.	Domain
