3.4.22.B74	(SUMO-1)-beta-galactosidase conjugate + H2O	SUSP1 expressed in Escherichia coli cells efficiently releases SUMO-1 from SUMO-1-beta-galactosidase fusion but not from other ubiquitin-like protein fusions, including Smt3-beta-galactosidase	Homo sapiens	SUMO-1 + beta-galactosidase	-	?	415960	
3.4.22.B74	(SUMO-3)-Ran GTPase-activating protein 1 conjugate + H2O	SENP6 and SENP7 prefer SUMO2 or SUMO3 in deconjugation reactions with rates comparable with those catalyzed by SENP2. In contrast to SENP2, SENP6 and SENP7 are less able to deconjugate SUMO1-RanGAP1, and products are only detected at enzyme concentrations 100 x higher than that observed for reactions containing SENP2	Homo sapiens	SUMO-3 + Ran GTPase-activating protein 1	-	?	415971	
3.4.22.B74	acetyl-LRGG-7-amido-4-trifluoromethylcoumarin + H2O	SENP6 prefers the LRGG sequence, residues typical of Nedd8 or ubiquitin in the P3 and P4 positions	Homo sapiens	acetyl-LRGG + 7-amino-4-trifluoromethylcoumarin	-	?	416497
