Q & A

Customer Q&As
Can glutamine be inserted into either part of the vector?

A: For TAGZyme cleavage, a glutamine should be inserted at an uneven amino acid position, followed by the first amino acid of the expressed protein.

What is the Lac promoter?

A: Lac promoter: It comes from the lactose operon of E. coli. It is a directional nucleotide sequence on a DNA molecule and consists of the repressor protein gene (LacI), initiator gene (P), manipulation gene (O) and the gene structure encoding three enzymes involved in lactose utilization

What is the regulatory mechanism of the Lac promoter?

A: The Lac promoter is positively regulated by the catabolic system and negatively regulated by repressors. Positive regulation activates the promoter through the CAP (catabolite gene activation protein) factor and cAMP to promote transcription. Negative regulation is the production of the LacZ repressor protein, which binds to the manipulated gene to prevent transcription.
