Trigger factor Protein, E.coli (P.pastoris, His)

Customer Review

Based on 1 Customer Validation

Trigger protein is essential for protein export, acting as chaperone and peptidyl prolyl cis-trans isomerase. In its chaperone role, it keeps nascent polypeptides in an open conformation, facilitating correct protein folding. Trigger factor Protein, E.coli (P.pastoris, His) is the recombinant E. coli-derived Trigger factor protein, expressed by P. pastoris , with N-His labeled tag.

Biological Activity

Description

Trigger protein is essential for protein export, acting as chaperone and peptidyl prolyl cis-trans isomerase. In its chaperone role, it keeps nascent polypeptides in an open conformation, facilitating correct protein folding. Trigger factor Protein, E.coli (P.pastoris, His) is the recombinant E. coli-derived Trigger factor protein, expressed by P. pastoris , with N-His labeled tag.

Background

Trigger factor protein is integral to protein export, serving a dual role as a chaperone that aids in the proper folding of newly synthesized proteins and as a peptidyl-prolyl cis-trans isomerase. In its chaperone capacity, trigger factor plays a crucial role in maintaining the nascent polypeptide in an open conformation, facilitating the intricate process of protein folding. Simultaneously, its peptidyl-prolyl cis-trans isomerase activity contributes to the isomerization of prolyl peptide bonds, further refining the conformational landscape of the emerging protein. This multifaceted involvement underscores trigger factor's significance in the intricate orchestration of cellular protein homeostasis and export mechanisms.
