Ptrc-CSAD

Description
P_trc-csad is a composite part consisting of the trc promoter and the csad sequences. This part was used in in vivo testing of taurine production. The sequence for csad and trc promoter were ligated and transformed into E. coli to calculate taurine production using high-performance liquid chromatography (HPLC).

Biology
trc promoter constitutively facilitates the expression of CSAD enzyme.

Usage

CSAD was used in in vivo testing of taurine production. The sequence for CDO1 enzyme and trc promoter were ligated and transformed into E. coli to calculate taurine production using high-performance liquid chromatography (HPLC).
