WebAbstract. An efficient method for purification of recombinant tryptophanase from Proteus vulgaris was developed. Catalytic properties of the enzyme in reactions with L-tryptophan … WebGut microbiota metabolizes tryptophan into indole, which can influence brain and behavior. Indeed, some oxidized derivatives of indole, formed in the liver, have neuroactive properties, and indole overproduction by the gut microbiota induces an anxio-depressive phenotype in rodents. The aim of this study was to investigate in humans whether there was a …

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.
