RESPIRATORY INHIBITOR FROM SERRATIA MARCESCENS.
Neufeld, Harold A. (U.S. Army Biological Laboratories, Fort Detrick, Frederick, Md.), Ronald L. Coleman, and Joseph S. Zannucci. Respiratory inhibitor from Serratia marcescens. J. Bacteriol. 85:614-618. 1963.-A substance was obtained from Serratia marcescens in conjunction with lipopolysaccharide that is a potent inhibitor of mammalian succinoxidase activity. It was determined that the purified lipopolysaccharide is not an in vitro inhibitor of the succinoxidase system. The inhibitor has no effect on succinic dehydrogenase or cytochrome oxidase but apparently exerts its effect on some portion of the electron-transport chain between the dehydrogenase and cytochrome c.
