Introduction
Tryptophanase,
also known as tnaA, catalyzes chemical reaction using 2 substrates which are L-tryptophan
and H2O. tnaA protein's three products are indole, pyruvate, and NH3.
Description
TNAA Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 494 amino acids (1-471) and having a molecular mass of 55.2kDa.
TNAA is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Source
E.coli.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
The TNAA solution (0.5mg/ml) contains Phosphate buffered saline (pH7.4), 10% glycerol and 1mM DTT.
