Target Mechanisms of the Cyanotoxin Cylindrospermopsin in Immortalized Human Airway Epithelial Cells

open access: yesToxins, 2022
Cylindrospermopsin (CYN) is a cyanobacterial toxin that occurs in aquatic environments worldwide. It is known for its delayed effects in animals and humans such as inhibition of protein synthesis or genotoxicity.

Substrate Specificity of Honeydew Melon Protease D, a Plant Serine Endopeptidase [PDF]

open access: yesBioscience, Biotechnology, and Biochemistry, 1997
The substrate specificity of honeydew melon (Cucumis melo var. inodorus Naud) protease D was studied by the use of synthetic substrates and oligopeptides derived from a protein hydrolyzate. The hydrolysis rates of succinyl-(L-Ala)1-3-p-nitroanilide (Suc-(Ala)1-3-pNA) the hydrolysis rate progressively rose in proportion to the increased chain length ...

Homologous inhibitors from potato tubers of serine endopeptidases and metallocarboxypeptidases. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1976
A potent polypeptide inhibitor of chymotrypsin has been purified from Russett Burbank potatoes. The inhibitor has no effect on bovine carboxypeptidases A or B but exhibits homology with a carboxypeptidase inhibitor that is also present in potato tubers.

Characterisation of proteins in excretory/secretory products collected from salmon lice, Lepeophtheirus salmonis

open access: yesParasites & Vectors, 2018
Background The salmon louse, Lepeophtheirus salmonis, is an ectoparasitic copepod which feeds on the mucus, skin and blood of salmonid fish species. The parasite can persist on the surface of the fish without any effective control being exerted by the ...

Alterations in gene expression of proprotein convertases in human lung cancer have a limited number of scenarios. [PDF]

open access: yesPLoS ONE, 2013
Proprotein convertases (PCs) is a protein family which includes nine highly specific subtilisin-like serine endopeptidases in mammals. The system of PCs is involved in carcinogenesis and levels of PC mRNAs alter in cancer, which suggests expression ...
