products 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. Recombinant E.coli SecB protein was expressed in E.coli and purified by using conventional chromatography.

ncbi summary :
Penultimate Ser residue missing from purified protein could be a proteolytic artifact. [More information is available at EcoGene: EG10937]. SecB is a cytoplasmic protein involved in the Sec secretion pathway and is believed to function in conjunction with SecA/E/G/Y to chaperone proteins in their unfolded state to the inner membrane secretion complex. [More information is available at EcoCyc: EG10937].
