Possible Interaction: Sodium Chloride and Polypeptides

“Furthermore, the 11- and 5-kDa polypeptide retained the antibacterial activities even at the physiological concentration of NaCl (0.15 M), although the antibacterial activity of defensin was completely lost in the presence of NaCl.”

“While chemically fractionating primary, human lymphocytes after challenge with cytotoxic doses of BCES, we detected a 12,900 M(r) polypeptide in 1.0 M NaCl extracts of exposed cells that was markedly increased compared to controls.”

“Coupling the peptides to the polypeptide significantly improved the anti-peptide antibody titer in Freund complete adjuvant or in NaCl 0.9%.”

“In all systems the two polypeptides showed a higher pressor or contractile activity in the presence of NaCl in the same solution than in pure water.”

“The mRNA levels from other chloroplast genes necessary for photosynthesis (psbD, … well as from several nuclear genes (pCab4, pCab1, rbcS) encoding polypeptides participating in photosynthesis, also increased in the salt-… when it was grown in the presence of NaCl whereas actin-mRNA and chloroplast-… comparable under growth conditions ± NaCl.”

“Moreover, the 60 and 44 kDa polypeptides seem to be salt responsive, since their concentration increases with increasing NaCl in the growth medium.”

“These include > 20 hitherto unreported rice polypeptides that exhibited a low abundance, short-term expression during NaCl stress.”

“The intensities of some of the polypeptide bands (molecular weights of 58, 37, 35.5, 34, 26, 21, 19.5, and 18 kilodaltons) increase with increasing levels of NaCl adaptation, while the intensities of other polypeptide bands (54, 52, 17.5, and 16.5 kilodaltons) are reduced.”
