Abstract

O-Diphenol: Oxygen-Oxidore ductase from Musa cavendishii. Rev. esp. Fisiol., 30, 167-176. 1974.

O-diphenol:O2-oxidoreductase from banana (Musa cavendishii) presents a certain degree of multiplicity. The enzyme is easily extractable with low ionic strength buffers (pH 6-6.5) and is not assumed to be associated with membranes. Ki values are higher in the order: cyanide, phenylhydrazine, dieca, azide (non-competitive inhibitor) and 8-hydroxyquinolin (competitive inhibitor). There is not a defined relationship between fruit ripening and enzymatic activity.
