Complex Formation Between Mycobacterial Polysaccharides and Fatty Acyl-CoA Derivatives

Yoshimasa Machida 1, Konrad Bloch 1
PMCID: PMC433444  PMID: 4515612

Abstract

The mycobacterial polysaccharides MMP and MGLP, which contain numerous O-methyl-sugar residues, markedly stimulate fatty acid synthesis catalyzed by a multienzyme complex from Mycobacterium phlei [Ilton, M. et al. (1971) Proc. Nat. Acad. Sci. USA 68, 87-91]. When aqueous solutions containing MMP or MGLP and palmitoyl-CoA were chromatographed on Sephadex G-75 under conditions that widely separate the individual components, polysaccharide and fatty acyl-CoA were eluted in a single peak, indicating formation of a molecular complex. Similarly, the mycobacterial polysaccharides associate with the CoA derivatives of C18, C20, and C22 acids to yield complexes containing maximally 1 mol of fatty acyl-CoA per mol of polysaccharide. The formation of these novel complexes may result from hydrophobic interactions between the paraffin chains of the acyl-CoA derivatives and O-methyl-sugar residues of the polysaccharides.

Keywords: O-methyl-sugar residues, Mycobacterium phlei, fatty acid synthesis
