The paper describes a new and gentle procedure for isolating "structural" phospholipoproteins from organisms and the first such isolation from a procaryotic microbe, Hydrogenomonas facilis. The amino acid composition of its protein moiety resembles that of "structural protein" from other sources. Although disc gel electrophoresis has shown the protein to be heterogeneous, this is attributed to aggregation.
