The membrane-bound hydrogenase of Alcaligenes eutrophus. I. Solubilization, purification, and biochemical properties

Abstract

The membrane-bound hydrogenase of Alcaligenes eutrophus was solubilized from washed membranes of autotrophically grown cells. The enzyme consists of two types of subunits and is an iron-sulfur protein. A flavin compound was not detected. The enzyme reacts only with few artificial electron acceptors.
