Research Abstract

We investigated Zea mayscytochrome b561 by employing the Pichia pastoris expression system to clarify the physiological roles of plant vacuole cytochromes b561 and the molecular mechanisms of their ascorbate-specific transmembrane electron transfer. We succeeded in expression and purification of Zea mayscytochrome b561. The detailed analyses of the electron transfer reactions with ascorbate and monodehydroascorbate radical by stopped-flow and pulse-radiolysis methods indicated that Zea mays cytochrome b561 has a similar molecular mechanism with that of animal neuroendocrine cytochrome b561 and that conserved amino acid residues have important roles for such ascorbate-specific transmembrane electron transfer reactions.
