Composite

Part:BBa_K2923013:Design

Designed by: Kateryna LEN   Group: iGEM19_Strasbourg   (2019-10-13)

Properties

This protein specifically recognizes the LexA operator sequence, which contains a mutated half-site (CCGT) with the LexA domain and links MS2-MS2-Aptazyme-PP7-PP7 by its MS2cp domain. LexA mutated repressor did not contain stop-codon.

Sources

This part corresponds to selected LexA mutated repressor (WT sequence coming from E. coli strain JL1434) [Dimitrova, M., Younès-Cauet, G., Oertel-Buchheit, P., Porte, D., Schnarr, M., and Granger-Schnarr, M.

Molecular and General Genetics MGG 257, 205–212.] PP7cp was amplified with overlapping sequences for Gibson assembly from BH3 plasmids [Berry, K.E., and Hochschild, A. (2018).
