  • Title: Biliverdin as an electron transfer catalyst for superoxide ion in aqueous medium.
    Author: Galliani G, Monti D, Speranza G, Manitto P.
    Journal: Experientia; 1985 Dec 15; 41(12):1559-60. PubMed ID: 3000813.
    Abstract:
    Stopped flow experiments gave evidence of the formation of a biliverdin-superoxide complex and/or a biliverdin radical anion by reaction of aqueous O2- with biliverdin. Such transient species are likely intermediates both in the bleaching of biliverdin, during exposure to the aerobic xanthine oxidase reaction, and in the reduction of ferricytochrome c under the same conditions.
