LacI Promoter Variant #3

Details

• Types: DnaRegion
• Roles: promoter; Regulatory
• Sequences: BBa_K611023_sequence (Version 1)

Description

Parts K611021 through K611027 are variants of the wild type LacI repressible promoter, BBa_R0010. These parts were generated through three rounds of mutagenic PCR and each have around 1 to 7 mutations. Each of these variants differ in properties such as transcriptional strength and repressor binding affinity and have been well characterized. This can be very useful in tuning genetic circuits for specific outputs.

Notes

We chose to mutate this part from a well known promoter so that any changes in behavior would be easy to observe.
