Probing the interaction of pepsin with imidacloprid via DFT calculation, spectroscopic approaches and molecular docking

, 2019
The use of the pesticide imidacloprid can be hazardous to human health. In this work, the impacts of imidacloprid on the secondary structure of pepsin were investigated through spectroscopic techniques and simulation studies.

Binding of triclosan and triclocarban to pepsin: DFT, spectroscopic and dynamic simulation studies.

Chemosphere, 2019
The use of antibacterial agents, triclosan (TCS) and triclocarban (TCC), in personal care products can result in direct human exposure. Density Functional Theory (DFT) was utilized to evaluate the electronic properties of TCS and TCC, and the determined ...

Coloured inhibitors of pepsin

Biochimica et Biophysica Acta (BBA) - Enzymology, 1967
It was shown that d iazoace ty l -D,L-nor leuc ine inactivates hog pepsin in the presence of copper ions at pH 5; moreover , one residue of the inhibitor is added to the enzyme molecule [1]. It is believed that the inhibitor es ter i f ies one of the carboxyl groups of the enzyme.

Pepsin-immunoregulation hypothesis

Medical Hypotheses, 1984
Pepsin exists in macrophages. Phagocytosis of foreign materials increases pepsin activity in macrophages and also causes extracellular release of pepsin from macrophages. Pepsin enhances antibody production by spleen cells against heterologous materials and suppresses that against homologous materials.

AN INSOLUBILISED PEPSIN

International Journal of Peptide and Protein Research, 1972
A highly active insoluble form of pepsin has been prepared for use in isolation of pepsin C inhibitor, a purpose for which it eventually proved ineffective. The preparation may be of interest to others.
