Effect of Glucose on the Formation of the Membrane-Bound Electron Transport System in Haemophilus parainfluenzae

Department of Biochemistry, University of Kentucky Medical Center, Lexington, Kentucky

ABSTRACT

The catabolism of glucose by Haemophilus parainfluenzae affected the formation of the primary dehydrogenases of the membrane-bound electron transport system. The formation of other components of the respiratory system, 2-demethyl vitamin K₂, cytochrome b₁, cytochrome c₁, and the cytochrome oxidases a₁, a₂, and o, is not affected by the catabolism of glucose. The formation of all components of the electron transport system is controlled by the identity and concentration of the terminal electron acceptors present in the growth medium.
