Sandwich ELISA for quantitative detection of human collagen prolyl 4-hydroxylase
BACKGROUND We describe a method for specific, quantitative and quick detection of human collagen prolyl 4-hydroxylase (C-P4H), the key enzyme for collagen prolyl-4 hydroxylation, in crude samples based on a sandwich ELISA principle. The method is relevant to active C-P4H level monitoring during recombinant C-P4H and collagen production in different expression systems. The assay proves to be spe...
متن کاملSelective Inhibition of Collagen Prolyl 4-Hydroxylase in Human Cells.
Collagen is the most abundant protein in animals. Its overproduction is associated with fibrosis and cancer metastasis. The stability of collagen relies on post-translational modifications, the most prevalent being the hydroxylation of collagen strands by collagen prolyl 4-hydroxylases (CP4Hs). Catalysis by CP4Hs enlists an iron cofactor to convert proline residues to 4-hydroxyproline residues,...
متن کاملBioavailable affinity label for collagen prolyl 4-hydroxylase.
Collagen is the most abundant protein in animals. Its prevalent 4-hydroxyproline residues contribute greatly to its conformational stability. The hydroxyl groups arise from a post-translational modification catalyzed by the nonheme iron-dependent enzyme, collagen prolyl 4-hydroxylase (P4H). Here, we report that 4-oxo-5,6-epoxyhexanoate, a mimic of the α-ketoglutarate co-substrate, inactivates h...
متن کاملComparison of Dot-ELISA and Sandwich ELISA Diagnostic Tests in Detection of Human Hydatidosis
Hydatidosis, caused by the larval stage of Echinococcus granulosus, is one of the most important zoonosis with worldwide distribution. As its diagnosis by clinical symptoms and scanning alone is difficult and confusing, we designed the present study to achieve a sensitive and simple diagnostic method for epidemiological studies. Sera (250 samples) were collected from 90 cases of hydatidosis pro...
متن کاملProlyl 4-hydroxylase.
Posttranslational modifications can cause profound changes in protein function. Typically, these modifications are reversible, and thus provide a biochemical on-off switch. In contrast, proline residues are the substrates for an irreversible reaction that is the most common posttranslational modification in humans. This reaction, which is catalyzed by prolyl 4-hydroxylase (P4H), yields (2S,4R)-...
