title: [Isolation of a protein fraction stimulating the exchange of branched chain fatty acids between the mesosomes and the protoplasts of Bacillus subtilits var. niger].
abstract: A new protein, stimulating in vitro the exchanges of branched chain fatty acids between mesosomes and plasma membranes, was isolated from periplasmic supernatant of B. subtilis. by gel filtration on a (Sephadex G 75) column. This protein, activating the exchanges, was only found during the exponential phase of the growth of the bacteria.
