Acciones bioquímicas o fisiológicas
DL-7-Azatryptophan is a racemic mixture of D- and L-7-azatryptophan which together with L-tryptophan is a synergistic inducer of tryptophan oxygenase of Pseudomonas acidovorans. DL-7-Azatryptophan inhibits photosynthetic carbon assimilation, photosynthetic oxygen evolution and nitrogen metabolism in Anabaena sp. Strain 1F, a marine filamentous, heterocystous cyanobacterium.

The tryptophan analogues 7-azaindole (7-Aza W) and 5-hydroxytryptophan (5-OH W) have a significant absorbance between 310-320 nm, which allows them to act as selective luminescence probes in protein mixtures containing a large number of tryptophan residues. To assess the potential

The phage lambda lysozyme (lambda L) contains four tryptophans. These have been efficiently replaced by 7-azatryptophan (7aW) through biosynthetic incorporation into the overexpressed protein. Comparative analysis of the effect of temperature or pH on the fluorescence of the wild-type lambda

The process of induction of tryptophan oxygenase in Pseudomonas acidovorans is typical of many microbial enzyme induction systems, in that it (i) requires cell multiplication and de novo protein synthesis, (ii) is subject to catabolite repression, (iii) results in the

The addition of DL-7-azatryptophan (AZAT), a tryptophan analog, to continuous cultures of Anabaena sp. strain CA grown with 10 mM nitrate as the nitrogen source resulted in the differentiation of heterocysts. Analysis of the intracellular amino acid pools of Anabaena

Fluorescence resonance energy transfer (FRET) provides a powerful means to study protein conformational changes. However, the incorporation of an exogenous FRET pair into a protein could lead to undesirable structural perturbations of the native fold. One of the viable strategies
