General description
Thimet oligopeptidase is considered essential in the degradation of collagen in collaboration with collagenolytic enzymes. Thimet oligopeptidase (TOP) is a neuropeptidase involved in the hydrolysis of gonadotropin-releasing hormone, a key component of the hypothalamic-pituitary-gonadal axis.
Application
Thimet oligopeptidase can be used for the degradation of collagen in combination with collagenases. It can also be used for the hydrolysis of neuropeptides such as bradykin, neurotensin, and amyliod-β-peptide. Thimet oligopeptidase has been used in a study to investigate the effect of acute cocaine administration in male rats on TOP specific activity and mRNA levels in prosencephalic brain areas related with the reward circuitry: ventral striatum, hippocampus, and frontal cortex.
Preparation Note
This enzyme has been affinity chromatographically purified using a niquel affinity column. It contains a 6-Histidine tag in its C-terminus.
A working solution of this enzyme can be prepared in 20 mM phosphate buffered saline solution, pH 7.0, or sterile and deionized water, pH 7.0.

Gonadotrophin-releasing hormone (GnRH) was first isolated in the mammal and shown to be the primary regulator of the reproductive system through its initiation of pituitary gonadotrophin release. Subsequent to its discovery, this form of GnRH has been shown to be

Protein interactions are crucial for most cellular process. Thus, rationally designed peptides that act as competitive assembly inhibitors of protein interactions by mimicking specific, determined structural elements have been extensively used in clinical and basic research. Recently, mammalian cells have

Thimet oligopeptidase (EC 3.4.24.15) is a zinc(II) endopeptidase implicated in the processing of numerous physiological peptides. Although its role in selecting and processing peptides is not fully understood, it is believed that flexible loop regions lining the substrate-binding site allow

Pz-peptidase A, from the thermophilic bacterium Geobacillus collagenovorans MO-1, hydrolyzes a synthetic peptide substrate, 4-phenylazobenzyloxycarbonyl-Pro-Leu-Gly-Pro-D-Arg (Pz-PLGPR), which contains a collagen-specific tripeptide sequence, -Gly-Pro-X-, but does not act on collagen proteins themselves. The mammalian enzyme, thimet oligopeptidase (TOP), which has comparable

Thimet oligopeptidase (EC 3.4.24.15, TOP) is a metallo-oligopeptidase that participates in the intracellular metabolism of peptides. Predictions based on structurally analogous peptidases (Dcp and ACE-2) show that TOP can present a hinge-bend movement during substrate hydrolysis, what brings some residues
