products description :
The Seventeen Kilodalton Protein (Skp) is a trimeric periplasmic chaperone that assists outer membrane proteins in their folding and insertion into membranes. This protein required for the efficient release of ompA from the inner membrane, the maintenance of its solubility in the periplasm, and, in association with lipopolysaccharide (LPS), for the efficient folding and insertion of ompA into the outer membrane. Recombinant E.coli Skp, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

17.9 kDa (162aa), confirmed by MALDI-TOF
ncbi summary :
The reported binding to DNA was an artifact due to the cationic nature of Skp. [More information is available at EcoGene: EG10455]. Skp is a periplasmic protein chaperone that binds to unfolded outer membrane proteins. [More information is available at EcoCyc: EG10455].
