Recombinant E.coli tnaA protein
TnaA, also known as Tryptophanase/L-cysteine desulfhydrase. Tryptophanase is an enzyme that catalyzes the chemical reaction. Thus, the two substrates of this enzyme are L-tryptophan and H2O, whereas its 3 products are indole, pyruvate, and NH3. Recombinant E. coli tnaA, fused to His-tag at N-terminus, was expressed in E. coli and purified using conventional chromatography techniques.
