CDO1-6xHis
Description
L-cysteine dioxygenase (CDO1) is an enzyme that weighs 23 kDa. CDO1 functions in the L-cysteine sulfinic acid taurine biosynthesis pathway, converting L-cysteine to L-cysteine sulfinic acid. [1]
Fig. 1. Taurine pathways in E. coli [1,2].
CDO1 is part of the L-cysteine sulfinic acid pathway, one of three possible taurine synthesis pathways. CDO1 oxidizes L-cysteine naturally found in the intestine into L-cysteine sulfinic acid, which is later converted to taurine by CSAD [1].
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
Fig. 2. PCR confirmation of cdo1-6xHis
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). A 6xHis-tag is added to the C-terminal of the CDO1 protein, allowing for confirmation of CDO1 expression by western blot using the anti-6xHis antibody.
