JJU
Description
JJU (cysteine lyase) is an enzyme weighing approximately 43.1 kDa. JJU catalyzes the beta replacement reaction of L-cysteine and sulfite to form L-cysteate and hydrogen sulfide[1].
Biology
The three taurine production pathways incorporated into our E. coli include the L-cysteine sulfinic acid pathway, L-cysteine sulfonic acid pathway, and the JJU-CoaBC pathway[1,2].

JJU is an enzyme that is part of the JJU-CoaBC taurine production pathway, one of three possible taurine synthesis pathways. Its main function is to convert L-cysteine to L-cystate, which then becomes taurine by CoaBC[1].
Usage
JJU enzyme was used in in vitro testing of taurine production. The sequence for JJU enzyme and trc promoter (BBa_K864400) were ligated and transformed into E. coli. By adding L-cysteine substrate into a reaction solution, JJU can help catalyze the conversion of L-cysteine to taurine. Taurine concentrations were determined using high-performance liquid chromatography (HPLC).
