Enzyme Function | FUNCTION: PSBY-1 and -2 are manganese-binding polypeptides with L-arginine metabolizing enzyme activity. They are a component of the core of photosystem II. They have also a minor catalase-like activity since they cause evolution of oxygen from hydrogen peroxide in a reaction stimulated by manganese. |
