Abstract:Protein analysis and electron microscopic observation of thefreeze-fractured plane of the plasma membrane were performedwith an acriflavine-sensitive mutant carrying mutation acrA(at min 10) and with the wild type (acrA+) strain of Escherichiacoli K-12. The acrA mutant membrane was deficient (or much lower)in one protein when analyzed by the polyacrylamide gel electrophoresistechnique. (Received May 7, 1981; Accepted July 28, 1981)
