Simon, Helmut

At first they feared the worst. A body embedded in glacial ice - what else could this be but the gruesome record of a climbing accident Or perhaps even, to judge from the apparent wound on the back of the dead man s head, something more sinister. Either way, Helmut and Erika Simon, hiking in the Alps along the border of Austria and Italy on 19 September 1991, were deeply disturbed by their discovery.

Stefan Neumann and Helmut Simon (from the Technical University of Munich) had discovered already in 1986 that the squalene-hopene cyclase from Alicydo-bacillus acidocaldarius [260] carries out the cyclisation, not only of squalene to hopene andhopanol, but also ofhomofarnesolto A/wfcrojc . [261] It may therefore be assumed, that this latter cydisation proceeds in a very similar way as in case of squalene.
