Separation of myocardial cytoplasmic acidic inhibitor proteins which inhibit hepatic protein biosynthesis in vitro.
Cytoplasmic inhibitor proteins of rabbit and pig myocardium have been separated and their in-vitro effects on hepatic cell-free protein biosynthesis reported. Three protein peaks could be separated from myocardial cytoplasmic pH 5 fraction by DEAE and CM cellulose column chromatography. There was a difference in the elution pattern of the acidic inhibitor proteins obtained from pig and rabbit myocardium. The myocardial acidic inhibitor proteins inhibited a liver cell-free protein biosynthesizing system, but not a myocardial cell-free system.
