Bacteriohopanetetrol: abundant lipid in frankia cells and in nitrogen-fixing nodule tissue

A M Berry et al. Plant Physiol. 1991 Jan.

Abstract

An unusual class of lipid with amphiphilic properties has been detected in nodule tissue of Alnus and Ceanothus. High levels of the same lipid (20-50% of total cell lipids) were detected in solvent extracts of Frankia spp. cells. However, the lipid was absent in host roots. The lipid was purified and quantified by high-performance liquid chromatography/flame ionization detector. Phenol-sulfuric acid determinations and proton nuclear magnetic resonance indicated that the purified lipid is not a glycolipid. Mass spectra of the predominant species are consistent with published spectra for bacteriohopanetetrol (C(35)H(62)O(4)), a pentacyclic triterpenoid, or hopanoid.
