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].
