CSAD

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

Biology
lacI promoter constitutively facilitates the expression of CSAD enzyme.

Usage
cdo1 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).

Characterization
The CDO1 fragment was synthesized by IDT and amplified by PCR. Agarose gel electrophoresis result is shown in Fig. 2.
