Crystal Structure of Glycyl Endopeptidase from Carica papaya: A Cysteine Endopeptidase of Unusual Substrate Specificity

Biochemistry, 1995
Glycyl endopeptidase is a cysteine endopeptidase of the papain family, characterized by specificity for cleavage C-terminal to glycyl residues only and by resistance to inhibition by members of the cystatin family of cysteine proteinase inhibitors. Glycyl endopeptidase has been crystallized from high salt with a substrate-like inhibitor covalently ...

Chinese hamster ovary cells continuously secrete a cysteine endopeptidase

In Vitro Cellular & Developmental Biology, 1990
The protease activity in serum-free conditioned medium of chinese hamster ovary (CHO) cells was measured using peptidyl (or aminoacyl)-4-methylcoumaryl-7-amides (MCAs) as the substrates. Aminopeptidase increased in level as amounts of nonviable cells increased during cultivation in serum-free medium, indicating that the activity seems to be originated ...

A high-molecular-weight cysteine endopeptidase from rat skeletal muscle

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1983
A cytosolic enzyme of high molecular weight (about 500 000), which attacks native or denatured proteins (inter alia, casein, globin and hexokinase) was purified about 1000-fold from mixed rat skeletal muscles, including muscles freed of mast cells by prior treatment of the animals with the degranulator, compound 48/80.

Endogenous Action of Cysteine Endopeptidase and Three Carboxypeptidases on Triticale Prolamins

Cereal Chemistry, 2008
ABSTRACTQuantitative and qualitative changes occurring in the prolamin fraction in the starchy endosperm of triticale grains were analyzed by SDS‐PAGE on consecutive days of germination. The most intensive hydrolysis of prolamins was observed after the second day of the process.

Molecular cloning and characterization of a cathepsin L-like cysteine protease of Angiostrongylus cantonensis.

International Journal of Biological Macromolecules, 2019
Angiostrongylus cantonensis is a parasitic nematode dwelling in the heart and pulmonary arteries of rats, which can cause angiostrongyliasis in human by accidental infections, manifested as eosinophilic meningitis or meningoencephalitis.

A cysteine endopeptidase from barley malt which degrades hordein

Phytochemistry, 1989
Abstract A cysteine endopeptidase of M r 29 000 which we have named malt endopeptidase-1 (MEP-1) was purified to homogeneity from a four-day green malt of barley ( Hordeum vulgare cv Schooner). It consists of two main species of pl 4.2 and 4.3 has a pH optimum of 4.5 for the hydrolysis of hordein and accounts for over a half of the hordein ...

Purification and partial characterization of a 31-kDa cysteine endopeptidase from germinated barley

Planta, 1996
Proteolytic enzymes hydrolyze cereal seed storage proteins into small peptides and amino acids, which are very important for seed germination and the malting process. A cysteine-class endopeptidase was purified from 4-d-germinated barley (Hordeum vulgare L. cv. Morex).

A RasMol study of the Mechanism of Inhibition of Cysteine Endopeptidase Enzyme Papain

Current Proteomics, 2009
Cysteine endopeptidases regulate many physiological processes in the body and their impaired function may lead to several diseases. One of the methods of treating such diseases is achieved by controlling the proteolytic activity of these enzymes by using enzyme inhibition.

The Inhibition of Interleukin 1-Stimulated Cartilage Proteoglycan Degradation by Cysteine Endopeptidase Inactivators

1993
Cysteine endopeptidase inactivators were tested as inhibitors of interleukin 1-stimulated proteoglycan release from bovine nasal septum cartilage explants. Hydrophilic inactivators showed no inhibition at concentrations up to 100 microM. In contrast, lipophilic inactivators gave significant inhibition, which was both reversible and specific. No effects
