Characterization and Structure of Pineapple Stem Inhibitor of Cysteine Proteinases

Biological Chemistry Hoppe-Seyler, 1992
The complete amino acid sequence of the inhibitor of cysteine proteinases from pineapple stem acetone powder was determined. The inhibitor consists of 52 amino acids and is composed of two polypeptide chains (41 and 11 amino acids) linked via disulphide bonds. It differs from already known sequences in one to four amino acids.

Cathepsin D inactivates cysteine proteinase inhibitors cystatins

Biochemical and Biophysical Research Communications, 1988
The formation of inactive complexes in excess molar amounts of human cathepsins H and L with their protein inhibitors human stefin A, human stefin B and chicken cystatin at pH 5.6 has been shown by measurement of enzyme activity coupled with reverse-phase HPLC not to involve covalent cleavage of the inhibitors.

Peptide Methyl Ketones as Reversible Inhibitors of Cysteine Proteinases

Journal of Enzyme Inhibition, 1989
Peptide methyl ketones represent a new class of reversible, competitive cysteine proteinase inhibitor with little or no effect on serine proteinases. The affinity of the inhibitors to papain (EC 3.4.22.3), cathepsin B (EC 3.4.22.1) and cathepsin L (EC 3.4.22.15) depends on the peptide chain length and on side-chain effects.

Antimalarial effects of vinyl sulfone cysteine proteinase inhibitors

Antimicrobial Agents and Chemotherapy, 1996
We evaluated the antimalarial effects of vinyl sulfone cysteine proteinase inhibitors. A number of vinyl sulfones strongly inhibited falcipain, a Plasmodium falciparum cysteine proteinase that is a critical hemoglobinase. In studies of cultured parasites, nanomolar concentrations of three vinyl sulfones inhibited parasite hemoglobin degradation ...

Cysteine proteinase inhibitors and bleomycin-sensitive and -resistant cells

Biochemical Pharmacology, 1991
We have isolated a new human head and neck carcinoma cell line (C-10E) that is highly resistant to BLM (40-fold) when compared to the parental (A-253) cell line. Consonant with BLM resistance in the C-10E cell line, we found that this cell line accumulated 2- to 3-fold less BLM A2 than A-253 cells.

Inhibitors of cysteine proteinases from potato.

Biological chemistry Hoppe-Seyler, 1989
Potato tubers contain considerable amounts of inhibitors of cysteine proteinases. The majority of inhibitory activity is due to low-molecular mass inhibitors differing in isoelectric points. Three of them were obtained in homogenous form, namely PCPIs (potato cysteine proteinase inhibitors) 6.6 (Mr 25,000), 8.3 and 9.4 (both Mr 22,000).
