quorum sensing controls the luminescence of vibrio fischeri through the transcriptional activator luxr and the specific autoinducer signal produced by luxi. amino acid sequences of these two genes were analyzed using bioinformatics tools. luxi consists of 193 amino acids and appears to contain five α-helices and six ß-sheets when analyzed by sspro8. luxi belongs to the autoinducer synthetase fa...

Abstract Carayannis and Campbell (2009; 2010) have argued for using quadruple quintuple helices as models encompassing generalizing triple-helix dynamics. In the meantime, been adopted by European Committee Regions Commission metaphors further strategy development such in EU-programs Smart Specialization, Plan S, Open Innovation 2.0, etc. Here we argue that transition from a double helix to tri...
