the properties of the isotropic and axial components ( hoffman , b.m. , roberts , j.e. , kang , c.h. , and margoliash , e. ( 1981 ) j. biol . chem . 256 , 6556-6564 ; hori , h. , and yonetani , t. ( 1985 ) j. biol . chem . 260 , 349-355 ) of the epr signal of the wild-type enzyme-peroxide complex , studied as a function of h2o2 stoichiometry , support proposals ( goodin et al . ( 1985 ) and hori and yonetani ( 1985 ) , see above ) that two distinct radical species are formed , and spin quantification shows that the isotropic radical is always formed in substoichiometric amounts .
