  • Title: [Trypsin and lipase activity in the presence of antibiotics].
    Author: Geĭtman IIa, Kardash BE, Kivman GIa.
    Journal: Vopr Med Khim; 1977; 23(5):632-5. PubMed ID: 595496.
    Abstract:
    Effect of penicillin, kanamycin and streptomycin on the proteolytic activity of trypsin using hemoglobin and casein as substrates as well as effect of these antibiotics and oxacilin, methycillin and tetracycline on the lipase activity were studied in vitro. Penicillin, kanamycin and streptomycin (5 mg, 20 mg and 80 mg of the antibiotic per 1 mg of trypsin, respectively) did not inhibit the proteolytic activity of the enzyme. Kanamycin slightly activated the trypsin activity in reaction with hemoglobin and streptomycin -- in reaction with casein. Penicillin, oxacillin and methycillin inhibited the lipase activity, when 80-100 mg of the antibiotics were used per 1 mg of the enzyme.
