Biochem/physiol Actions

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 analogs 5-hydroxytryptophan (5HW) and 7-azatryptophan (7AW) are capable of being biosynthetically incorporated into bacterial proteins and can be used as intrinsic fluorescence probes of protein structure, function and dynamics. A prerequisite for analog incorporation is their recognition by

Aequorea victoria green fluorescent protein and its widely used mutants enhanced green fluorescent protein and enhanced cyan fluorescent protein (ECFP) are ideal target proteins to study protein folding. The spectral signals of their chromophores are directly correlated with the folding

In vivo expression of colored proteins without post-translational modification or chemical functionalization is highly desired for protein studies and cell biology. Cell-permeable tryptophan analogues, such as azatryptophans, have proved to be almost ideal isosteric substitutes for natural tryptophan in cellular

The amino acid analogue 7-azatryptophan has attracted significant recent attention as a novel optical probe for protein structure, function and dynamics. We report here, for the first time, its fluorescence emission behavior in a membrane mimetic model system, namely reverse

Three zinc metallopeptidases are implicated in the regulation of fluid homeostasis and vascular tone and represent interesting targets for the treatment of chronic heart failure. We have previously reported the synthesis of a triple inhibitor able to simultaneously inhibit neprilysin
