Molecular biology has become an integral part of the diagnosis of infectious diseases. Recently, quantitative real-time PCR (QPCR) methods (often in the form of so-called TaqMan® systems) have been developed for the diagnosis of a wide range of infectious diseases; these techniques
Voltage-gated ion channels are fundamental for electrical signaling in living cells. They are composed of four subunits, each holding six transmembrane helices, S1-S6. Each subunit contains a voltage-sensor domain, S1-S4, and a pore domain, S5-S6. S4 contains several positively charged amino-acid residues

Cyclotides are a family of small and macrocyclic proteins that have been found in Violacaee and Rubiaceae plant species. These proteins contain a cystine knot: two disulfides bonds together with their connecting peptide backbone form an embedded ring which is penetrated by
