28461152-2	2017	The azide anion is a potent competitive inhibitor that binds directly to the metal and is used as a substrate analog to superoxide in studies of SOD.	Superoxides	120-130	superoxide dismutase 2	Homo sapiens	145-148	
28461152-3	2017	The crystal structure of human MnSOD-azide complex was solved and shows the putative binding position of superoxide, providing a model for binding to the active site.	Superoxides	105-115	superoxide dismutase 2	Homo sapiens	31-36
