Small RNA spot42

This part is a component of the Uppsala University iGEM 2012 modular small RNA screening system, together with the target construct BBa_K864444.

This is the small RNA spot42 from E coli MG1655 coupled to the strong promoter BBa_J23101. The spot42 regulates the galactose metabolism by binding to the mRNA and recruiting Hfq proteins [1], blocking initiation of translation. The spot42 has proven to be an especially suitable sRNA for engineering of silencing sRNA:s, by replacing its RNA-binding domain[2].

To create a random sRNA library, the RNA-binding domain can be randomized by site-directed mutagenesis using the primers BBa_K864445 and BBa_K864446.
