LITERATURE
3 enzyme forms ASSI, ASSII, and ASSIII
-
affinity chromatography
analysis by native gel electrophoresis shows that argininosuccinate synthetase can bind bacterial lipopolysaccharide and lipid A
-
argininosuccinate synthetase is purified from mouse liver. Livers are excised from 20 male mice (C3H/He strain, age 7-8 weeks) and homogenized in 100 mM Tris-HCl (pH 7.5) containing 1 mM citrulline and 1 mM aspartic acid. Homogenate is centrifuged. After salting-out with (NH4)2SO4. The sample is subjected to anion-exchange chromatography on DE-52. Concentrated samples are loaded on a column of Sephacryl S-300 HR. The collected first peak fractions are dialyzed and subjected to anion-exchange chromatography on UNO S-1
