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.

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

The villin headpiece subdomain (HP35) has become one of the most widely used model systems in protein folding studies, due to its small size and ultrafast folding kinetics. Here, we use HP35 as a test bed to show that the
