Abstract

Respiratory chain composition of the ethanol-producing bacterium Zymomonas mobilis was studied. Its membrane D-lactate oxidase was characterised. With NADH, but not D-lactate as substrate, a cytochrome o-like component was seen in CO difference spectra. Chlorpromazine specifically inhibited reduction of cytochrome d, while myxothiazol eliminated the cytochrome o-like features in CO difference spectra. It is suggested that electrons from NADH are distributed between branches terminatedby the cytochrome o-like component, cytochrome a, and cytochrome d With D-lactate, electrons are transported to cytochrome a, or an unidentified CN--sensitive oxidase, and cytochrome d.
