ParaBAD-tyrosinase:AIDA-terminator

Tyrosinase fused to AIDA autotranporterBBa_K3505006 for outer membrane exxpression[2]. Uder control of constitutive Anderson promoterBBa_K3505012.

Fig.1:The Tyrosine Tyrosinase Reporter Module


Usage and Biology

This Transcripion Unit is an electrochemical reporter module [1]. L-Tyrosine is converted to L-Dopa and L-Dopa quinone which is electrochemical detectable. This electochemical signal has the advantage of high quality and easy digitalization. The only advamtage is that is not well characterized.

Verification of the cloning

Fig.2:pAndersonJ23115:RBS-tyrosinase:AIDA-terminator Digested with BamHI. Expected bands 2847, 1883, 520, 353


Experimental Use and Experince

The Tyrosinase assay from the literature [1] is the addition of 1 g/L of L-Tyrosine into liquid cultures and incubation for 6 hours at 30 celcius.

Measurements are the average of 9 total replicates (3 biological replicates and 3 technical replicates per biological replicate). Error bars represent standard deviation of biological replicates

The constitutive Promoter led to toxicity so we plan next year to add an inducble one
