Abstract:
:ADP-ribosylation by cholera toxin of the guanine nucleotide binding regulatory protein (Gs) of rat liver membrane adenylate cyclase was inhibited by 0.1-1 mM MDL 12330A or 0.1-1 mM chlorpromazine. Basal as well as cholera toxin activated adenylate cyclase activity in liver membranes was also inhibited by the two drugs. NAD glycohydrolase activity and self-ADP-ribosylation of cholera toxin were also inhibited by MDL 12330A and chlorpromazine. These effects of MDL 12330A and chlorpromazine may be related to their effects on cholera toxin-induced fluid secretion in vivo.

杂志文章abstract::hPepT1 is a proton-coupled peptide transporter that mediates the absorption of di- and tripeptides. Here we show that tyrosine 167 (Y167) in transmembrane domain 5 (TMD5) of this 12-transmembrane spanning protein contributes to its transport function. We identified this particular amino acid by a computer model of the...
