This biotin-tagged SUMO protease product is designed to be used for on-column cleavage of SUMO fusion proteins. This method specifically cleaves the protein of interest from a column-bound SUMO fusion protein, leaving the SUMO domain bound to the affinity column (e.g. Ni-NTA column) and eluting only the protein of interest. This method is advantageous to post-elution cleavage for several reasons: Eliminates most of the impurities normally associated with purification on Ni-chelating columns. Allows much gentler elution conditions, with an added flexibility in the composition of the elution buffer. Assist preventing protein aggregation and inactivation. Following cleavage, the protease can be efficiently removed by using any avidin-conjugated or streptavidin-conjugated beads. This biotin-tagged SUMO protease has been enzymatically biotinylated without affecting its proteolytic activity. It does not include any additional protein purification tag (e.g., histidine-tag or GST).应用： SUMO proteases are enzymes that specifically cleave the post-translational protein modification (PTM) known as small ubiquitin-related modifier (SUMO). SUMO falls into the PTM class of ubiquitin and/or ubiquitin-like proteins (UBL).SUMO protease is the Ubl-specific protease 1 (Ulp1) from Saccharomyces cerevisiae. This was the first of this class of enzymes to be isolated. SUMO protease cleaves specifically the SUMO moiety in a ‘scarless′ manner. After recognizing the tertiary structure of the Ubiquitin-like SUMO domain, SUMO protease hydrolyzes the peptide bond in the x–Gly–Gly–x sequence after the Gly-Gly bond, at the C-terminus of the SUMO domain. Besides the cleavage of natural SUMO-modified proteins, SUMO protease is used to cleave recombinant SUMO fusion proteins. The SUMO domain is a known solubility-enhancing fusion tag used in recombinant protein expression. Since this recombinant protease does not contain any coman protein purification tag it can be used for on-column cleavage of column bound SUMO fusion protein. Sumo protease with Biotin tag can be easily removed at the end of the digestion reaction.
