Proposal
Iron sulfur cluster regulator (IscR) is an Fe-S protein that functions as a transcriptional regulator of Fe-S production and other Fe-S protein encoding genes in Escherichia coli (E. coli.). IscR controls the expression of more than 40 genes in E. coli (1). The purification of IscR for studying its many properties in E. coli is a well known technique. Recently, Atomic Force Microscopy (AFM) has provided a means of studying receptor ligand interactions that were once not available to us. Using the NTA-His6 system as a platform for the isolated protein and DNA has shown promise of being an efficient way to study desired single-molecule interactions in a stable manner with AFM (2). We thus plan to use His-tag sequencing to bind our IscR protein and DNA to a nickel platform and investigate the binding strength of IscR to DNA using AFM techniques.
