1934147-13	1991	In the latter reaction SOD is thought to be reduced by semiquinone with Q formation.	semiquinone	55-66	superoxide dismutase 1	Homo sapiens	23-26	
12065648-3	2002	The EPR signal corresponding to the DOPAC semiquinone was modulated as follows: (i) it was suppressed by glutathione and ascorbic acid with the formation of new EPR spectra corresponding to the glutathionyl and ascorbyl radical, respectively; (ii) it was enhanced by Cu,Zn-superoxide dismutase; the enzyme also accelerated the decay of the semiquinone species to DOPAC quinone.	semiquinone	42-53	superoxide dismutase 1	Homo sapiens	267-293	
2154955-6	1990	This indicates that SOD causes the equilibrium between semiquinone and superoxide to shift, resulting in a decrease of the semiquinone concentration.	semiquinone	55-66	superoxide dismutase 1	Homo sapiens	20-23
