产品名称：Recombinant E. coli Lactose Operon Repressor/LacI (C-6His)

描述: Recombinant E.coli Lactose operon repressor is produced by our E.coli expression system and the target gene encoding Met1-Gln360 is expressed with a 6His tag at the C-terminus.

背景说明: 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.
