1. A cell-free system from the bacterium Acetobacter pasteurianum was incubated with [12-3H]squalene; diploptene and diplopterol, hopanoids normally present in the bacterium, were labelled. Their radioactivity was confirmed by purification using thin-layer chromatography, synthesis of derivatives and recrystallization to constant

Most quantum mechanical studies of triterpene synthesis have been done on small models. We calculated mPW1PW91/6-311+G(2d,p)//B3LYP/6-31G* energies for many C30H51O+ intermediates to establish the first comprehensive energy profiles for the cationic cyclization of oxidosqualene to lanosterol, lupeol, and hopen-3beta-ol. Differences

With the help of a PCR-based screening method, the gene encoding squalenehopene cyclase (SHC) of Bradyrhizobium japonicum USDA 110 was isolated from a cosmid library. The SHC catalyses the cyclization of squalene to hopanoids, a class of triterpenoid lipids recently

The cyclization of the A-B rings of squalene to hopene is studied computationally (DFT). A transition structure is found for a concerted, asynchronous pathway for the formation of chair-chair decalin carbocation. The computationally derived conformer leading to this asynchronous transition

The membrane protein squalene-hopene cyclase was cocrystallized with 2-azasqualene and analyzed by X-ray diffraction to 2.13 A resolution. The conformation of this close analog was clearly established, and it agreed with the common textbook presentation. The bound squalene undergoes only
