Structural highlights 3eay is a 1 chain structure with sequence from Human. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Ligands: Gene: SENP7, KIAA1707, SSP2, SUSP2 (HUMAN) Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [SENP7_HUMAN] Protease that deconjugates SUMO2 and SUMO3 from targeted proteins, but not SUMO1. Catalyzes the deconjugation of poly-SUMO2 and poly-SUMO3 chains. Has very low efficiency in processing full-length SUMO proteins to their mature forms.

Publication Abstract from PubMed Small ubiquitin-like modifier (SUMO) proteases regulate the abundance and lifetime of SUMO-conjugated substrates by antagonizing reactions catalyzed by SUMO-conjugating enzymes. Six SUMO proteases constitute the human SENP/ULP protease family (SENP1-3 and SENP5-7). SENP6 and SENP7 include the most divergent class of SUMO proteases, which also includes the yeast enzyme ULP2. We present the crystal structure of the SENP7 catalytic domain at a resolution of 2.4 angstroms. Comparison with structures of human SENP1 and SENP2 reveals unique elements that differ from previously characterized structures of SUMO-deconjugating enzymes. Biochemical assays show that SENP6 and SENP7 prefer SUMO2 or SUMO3 in deconjugation reactions with rates comparable with those catalyzed by SENP2, particularly during cleavage of di-SUMO2, di-SUMO3, and poly-SUMO chains composed of SUMO2 or SUMO3. In contrast, SENP6 and SENP7 exhibit lower rates for processing pre-SUMO1, pre-SUMO2, or pre-SUMO3 in comparison with SENP2. Structure-guided mutational analysis reveals elements unique to the SENP6 and SENP7 subclass of SENP/ULP proteases that contribute to protease function during deconjugation of poly-SUMO chains.
