Numerous Gram-positive and Gram-negative bacterial species synthesize indole from tryptophan by tryptophanase.
The indole test is a biochemical test performed on bacterial species to determine the ability of the organism to convert tryptophan into indole. This division is performed by a chain of a number of different intracellular enzymes, a system generally referred to as "tryptophanase." See more Indole is generated by reductive deamination from tryptophan via the intermediate molecule indolepyruvic acid. Tryptophanase catalyzes the deamination reaction, during which the amine (-NH2) group of the … See more Like many biochemical tests on bacteria, results of an indole test are indicated by a change in color following a reaction with an added reagent.
