Lorca, GL; Ezersky, A; Lunin, VV; Walker, JR; Altamentova, S; Evdokimova, E; Vedadi, M; Bochkarev, A; Savchenko, A Glyoxylate and pyruvate are antagonistic effectors of the Escherichia coli IclR transcriptional regulator. J Biol Chem 282:16476-91 (2007) [PubMed] Article
Cell React
Source:
His-tagged fusion protein was overexpressed and purified in E. coli.
Prep. Method:
The His6 tag was cleaved from the protein by tobacco etch virus protease. The cleaved protein was then resolved by flowing the mixture through a second Ni2+ column. The purified proteins were dialyzed and concentrated.
