WebSep 18, 2007 · To investigate the effect of side chain length of Lys on ion-pairing interactions, a series of 12 monomeric alpha-helical peptides containing potential Glu-Xaa (i, i+3), (i, i+4) and (i, i+5) (Xaa = Lys, Orn, Dab, Dap) interactions were studied by circular dichroism (CD) spectroscopy at pH 7 and 2. At pH 7, no Glu-Xaa (i, i+5) interaction was ... WebAug 2, 2007 · It is concluded that virulence correlates with upregulation of key genes involved in stress response, including molecular chaperones, ssp1 and peroxiredoxin; as well as the induction of unknown genes encoding lysine‐rich proteins.
