Further Information

Abbreviation:
LacI
Accession:
P03023
Background:
Lactose operon repressor (LacI) contains one HTH lacI-type DNA-binding domain, functions as a homotetramer. Lactose operon repressor as a repressor of the lactose operon, which also as an inducer, binds allolactose. If remove residues 1-59, resulting the loss of DNA-binding activity but retains tetrameric structure and inducer-binding activity. If delete residues 340-360, resulting the loss of tetramer formation, but retains dimer formation, inducer-binding activity, and DNA-binding activity.
Calculated MW:
39.4 kDa
Endotoxin:
< 1.0 EU per ug of the protein as determined by the LAL method.
