LacI, E.coli (His-SUMO)

LacI, the lactose operon repressor, regulates lactose metabolism by binding to the operator region and repressing gene transcription. The presence of the inducer, allolactose, alters its binding affinity, derepressing the operon. As a homotetramer, LacI finely tunes lactose metabolism, orchestrating regulatory mechanisms in response to the cellular environment. LacI Protein, E.coli (His-SUMO) is the recombinant E. coli-derived LacI protein, expressed by E. coli , with N-His, N-SUMO labeled tag. The total length of LacI Protein, E.coli (His-SUMO) is 360 a.a., with molecular weight of ~54.6 kDa.
