LacI

Figure 1 Solution structure of a dimer of Lac repressor DNA-binding domain complexed to its natural operator O1 ([http://www.rcsb.org/pdb/explore.do?structureId=1L1M From RCSB])

The sequence produce LaLa repressor protein which is based on natural lacR with only several point mutations. Standard BioBrick Prefix and Suffix are added to both ends of this part for standard assembly.


Usage and Biology

LaLa could strongly inhibit its corresponding operator which is based on natural lac operator with only several point mutations while it has also weak inhibition to natural lac operator.
