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. [1]

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. [2]

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.

Protein degradation by the ubiquitin proteasome system releases large amounts of oligopeptides within cells. To investigate possible functions for these intracellularly generated oligopeptides, we fused them to a cationic transactivator peptide sequence using reversible disulfide bonds, introduced them into cells

Thimet oligopeptidase (TOP) and prolyl endopeptidase (PEP) are neuropeptidases involved in the hydrolysis of gonadotropin-releasing hormone, a key component of the hypothalamic-pituitary-gonadal axis. GnRH is regulated in part by feedback from steroid hormones such as estradiol. Previously, we demonstrated that

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
