To identify functionally relevant amino acids in the rat organic cation transporter 1 (rOCT1), 18 consecutive amino acids in the presumed fourth transmembrane alpha helix (TMH) were mutated and functionally characterized after expression in Xenopus laevis oocytes. After mutation of three amino acids on successive turns of the alpha helix, K(m) values for tetraethylammonium (TEA) and/or 1-methyl...

N-ethylmaleimide-sensitive fusion protein (NSF) and alpha-SNAP play key roles in vesicular traffic through the secretory pathway. In this study, NH2- and COOH-terminal truncation mutants of alpha-SNAP were assayed for ability to bind NSF and stimulate its ATPase activity. Deletion of up to 160 NH2-terminal amino acids had little effect on the ability of alpha-SNAP to stimulate the ATPase activi...

Isoelectric solubilization /precipitation (ISP) process was used to isolate protein from muscles of Prussian carp, Carassius gibelio (Bloch, 1782). Fish protein and lipid were recovered from whole gutted Prussian carp using acidic and basic isoelectric solubilization/precipitation followed by assaying amino acid and fatty acid profile. Essential amino acids content in acidic and basic pH treatm...
