... acid. Indolepyruvate decarboxylase, the key enzyme in the biosynthetic pathway of indole- 3 -acetic acid, catalyses the formation of indole- 3-acetaldehyde and carbon dioxide from indole- 3-pyruvic acid. The enzyme ... concentration and independent of the concentration of the auxiliary enzyme, confirming that the coupled assay monitors the true rat...
