Description
Escherichia coli lacZ' gene encoding the first 77 amino acids of LacZ (beta galactosidase), with a strong synthetic ribosome binding site. Complements the common lacZ-delta-M15 mutation found in many laboratory strains of E. coli, allowing blue-white selection. Note the presence of a SacI site at the 5' end, overlapping the XbaI site; this is preserved when this biobrick is added to any other biobrick.
Notes
Note the presence of a SacI site at the 5' end, overlapping the XbaI site; this is preserved when this biobrick is added to any other biobrick. The lacZ' gene was truncated by alteration of codon 77 from TGC to TGA (note: not TAATAA as recommended, due to an error; however, the part works fine).
