8634298-8	1996	We show that phenylarsenoxides potently inhibit E2-230K, apparently by binding to vicinal Cys residues of the enzyme: bound aminophenylarsenoxide partially protects the enzyme against inactivation by N-ethylmalemide (NEM), and prior enzyme inactivation with NEM blocks enzyme binding to immobilized phenylarsenoxide.	Cysteine	90-93	ubiquitin conjugating enzyme E2 O	Homo sapiens	48-55	
23455153-4	2013	We showed that UBE2O functions as an E2-E3 hybrid to monoubiquitinate SMAD6 at lysine 174 and that the cysteine 885 residue of human UBE2O is necessary for SMAD6 monoubiquitination.	Cysteine	103-111	ubiquitin conjugating enzyme E2 O	Homo sapiens	15-20
