Product Name
Recombinant E.coli Protein Export Chaperone
Product Overview
Recombinant E.coli SecB protein was expressed in E.coli and purified by using conventional chromatography, 17.2 kDa (155aa).
Description
SecB, a remarkable chaperone involved in protein export, binds diverse ligands rapidly with high affinity and low specificity. It plays a crucial role during protein export via the general secretory pathway by modulating the partitioning of precursors between folding or aggregation and delivery to the membrane-bound translocation apparatus. SecB has the potential to participate in functions outside of export acting as a general nonspecific chaperone to provide buffering capacity of the nonnative state of proteins in the cytosolic pool.
