title: [Disulphide bond in rabbit muscle phosphofructokinase].
abstract: A comparative study was performed for rabbit muscle phosphofructokinase (PFK) from normal and atherosclerotic animals. The diagonal electrophoretic technique was used for cysteic acid containing peptides separation. On performic acid oxidation among the tryptic peptides of PFK the disulphide containing peptide was found. Its electrophoretic mobility, compared to that of cysteic acid, gives ground for intrasubunit disulphied bond existence.
