Abstract

Cathepsin A has been demonstrated in cod muscle. Cathepsins A and D were partially separated and purified from cod muscle. Cathepsin A and D are essentially similar to those from other sources. Cathepsin A acts optimally on the synthetic substrate CBZ‐α‐L‐glutamyl‐L‐tyrosine at pH 5.0, whereas cathepsin D hydrolyses haemoglobin optimally at pH 3.8. Cathepsin D did not hydrolyse the synthetic peptides acted upon by cathepsins A, B or C.
