[Isoenzyme composition of cathepsin D from bovine hypothalamus]. / Izofermentnyi sostav katepsina D iz gipotalamusa byka.

The isoenzyme composition of cathepsin D from bovine hypothalamus was studied by isoelectric focusing. It was found that the soluble fraction of hypothalamic proteins contains five peaks of endopeptidase activity at pH 3.2. The properties studied allowed to identify these peaks of endopeptidase activity as isoenzyme forms of cathepsin D.
