Ptrc-CDO1
Description
Ptrc-cdo1 is a composite part consisting of the trc promoter and the cdo1 sequences. This part was used in in vivo testing of taurine production. The sequence for cdo1 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 CDO1 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).

In Vivo Test 1: Choosing a Growth Medium Since the intestine is not as nutrient-rich as LB (lysogeny broth), we chose to test taurine production in both LB and M9 (minimal salts) mediums. M9 consists of fewer nutrients than LB and more closely mimics the nutrient composition of the human intestine. First, Ptrc-cdo1 (BBa_K3771075), PlacI-csad (BBa_K3771076), and Ptrc-cs (BBa_K3771078) were transformed into DH5α strain. In another sample, only Ptrc-cdo1 and Ptrc-csad (BBa_K3771077) were transformed. The two samples were each grown in LB with IPTG inducer (LB+), M9 with IPTG inducer (M9+) , and M9 without IPTG inducer (M9-) mediums. The samples’ respective growth curves are shown in figure 21 and 22. Interestingly, the sample with all three enzymes (Ptrc-cdo1 +PlacI-csad +Ptrc-cs) had a lower growth rate in M9+ medium than in M9- medium. In the sample with two enzymes (Ptrc-cdo1+Ptrc-csad), M9 medium with or without an inducer added produced similar growth curves. Both samples grew best in LB (Fig. 11, 12)
