title: Cinnabarinate synthase from baboon (Papio ursinus) liver. Identity with catalase.
abstract: The enzyme chinnabarinate synthase was purified from the nuclei of baboon liver. Two purified fractions were obtained that exhibited a typical haem protein absorption spectrum; a probable identity with catalase was demonstrated. It was confirmed that catalase in the presence of Mn2+ produces cinnabarinate from 3-hydroxyanthranilate. Doubt is expressed on the existence of a distinct cinnabarinate synthase enzyme.
