The complete DNA sequence of the gene cluster coding for the microginin synthetase of the cyanobacterium Microcystis aeruginosa has been identified and sequenced for the first time. The microginin synthetase is a large multi-enzyme complex which catalyzes the microginin, a small linear lipopeptide belonging to the group of non-ribosomal synthesized peptides. <br><br> Microginins are synthesized by various species of cyanobacteria (“blue-green algae”) in diverse structure variants. Mircroginins represent an interesting group of unusual peptides in view of medical application as they are known to have inhibitory effects on the Angiotensin-Converting- Enzyme (ACE). Thus, microginins are potential ACE-inhibitors and represent important drug candidates to treat hypertension and associated diseases such as chronic heart failure and diabetic nephropathy.<br><br> The new identified DNA-sequence of the microginin synthetase gene cluster can be used to identify homologue gene cluster in other cyanobacteria spe-cies and as a matter of fact for the detection of new microginin variants or microginin-like structures. Further on, novel microginin variants can be gen-erated by gene biocombinatoric experiments (gene shuffling) with the objec-tive to optimize the ACE-inhibitory effect.

Self-driving cars will be on our streets in the foreseeable future. In Graz, research is currently dedicated to an innovative driver assistance system that takes over control if there is a danger of collision. It was nature that inspired Dr Manfred Hartbauer from the Institute of Zoology at the University of Graz: in dangerous traffic situations, migratory locusts react around ten times faster than humans. Working together with an interdisciplinary team, Hartbauer is investigating an affordable collision detector that is equipped with artificial locust eyes and can recognise potential crashes in time, during both day and night.
