| Do Cyanobacteria Contain a Membrane Bound Cysteine Oxidase? Department o f Cell Physiology and Im m unology* and Department o f M  | | | Abstract
| The oxidation o f cysteine with 0 2 is facilitated by isolated membranes o f the cyanobacteria A nacystis nidulans and Anabaena variabilis, and further stimulated by Fe3+. This reaction accelerates with increasing the pH value and is suppressed by cyanide, benzylhydroxamate, hydroxylamine, but not azide. The agents m entioned inhibited the respiration o f the m embranes with ascorbate and N ,N ,N',N'-tetram ethyl-p-phenylenediam ine (TM PD) effectively, but did not influence their nonenzym ic oxidation. It is inferred that ascorbate in com bination with TM PD is oxidized via membrane oxidases. Cysteine oxidation apparently proceeds non-enzym atically and is catalyzed by the cations o f heavy metals. | | |
