Mutagenesis of Tyr420 to Ala in the catalytic cavity of squalene-hopene cyclase of Alicyclobacillus acidocaldarius resulted in an altered product spectrum. Besides hopene and diplopterol, this mutant produced significant amounts of the bicyclic α- a

Amino acid residues lining the catalytic cavity of squalene-hopene cyclase of Alicyclobacillus acidocaldarius have been mutated. Alterations of His451 to Ala and Trp489 to Ala resulted in reduced enzymatic activity, while the product patterns were id

The double bond of dodecenoic acid in the endotoxin-antagonistically acting lipid A of Rhodobacter capsulatus, strains 37b4 and St Louis, was found to have cis-configuration. The position of the double bond was ω7. The mono-unsaturated fatty acids o
