Additional information was obtained on the sensitivity of this test and the time-dependent production of indole by tryptophanase.doi:10.1007/BF00443237M R KarimS. M. Hussain QadriD J FlournoyAntonie Van Leeuwenhoek
Add 2.0 ml of Reagent G (Toluene) tothe Test, Test Blank, and Substrate Blank. Mix vigorously to phase extract the liberated indole. Allow the phasesto separate. The toluene layer will be the upper layer.Pipette (in milliliters) the following reagents intosuitable containers...
The spectral changes and the NaBH4 test indicate that cooling of tryptophanase leads to breaking of the internal aldimine bond and release of the coenzyme. HPLC analysis showed that the ensuing apoenzyme dissociates into dimers. The dissociation depends on the nature and concentration of anions in ...
In all cases the inactivation is accompanied by a decrease of the coenzyme 420-nm CD and absorption peaks and a shift of the latter peak to shorter wavelengths. The spectral changes and the NaBH_4 test indicate that cooling of tryptophanase leads to breaking of the internal aldimine bond and...
