Part:BBa_K2448036

pSB1C3 BsmBI free

This part is the pSB1C3 backbone vector with a single synonymous (G1385C) mutation within the chloramphenicol resistance gene that eliminates the BsmBI cloning site.

Usage and Biology

BsmBI is a type IIS restriction enzyme used in the Golden Gate assembly [1]. Its presence in the backbone of the pSB1C3 plasmid prevents from using this high-throughtput assembly technique with this vector.

For this reason, we decided to perform a site-directed mutagenesis and disrupt the BsmBI recognition site CGTCTC by changing its sequence to CGTGTC. This site is present in the chloramphenicol resistance gene so care was taken that the mutation should not affect the amino acid composition of the protein. The chosen mutation is a synonymous one GTC(Val) to GTG(Val).

A relevant application of this part would be the use with it with our Universal Biosensing Chassis (BBa_K2448023 and BBa_K2448024) to build a transcription factor based biosensor finely regulated.
