Chains	Enzyme Name	Description	Catalytic Residues
A, B	tryptophanase M-CSA #410	Tryptophan indole-lyase (also known as tryptophanase or Trpase) is a pyridoxal 5'-phosphate (PLP) dependent enzyme that catalyses the reversible beta-elimination reaction of L-Tryptophan to form indole and ammonium pyruvate. The enzyme has been found in a wide variety of Gram-negative bacteria.
