Actions biochimiques/physiologiques

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

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

Aal and 7-Atrp, quasi-isosteric with Trp, have been inserted together with a TOAC residue in two 3(10)-helical, model hexapeptides. The interaction of photoexcited AA1 and 7-Atrp with the nitroxide group of TOAC was investigated by time resolved EPR. Both peptides
Vasant Muralidharan et al.

An integrated approach is described that allows the domain-specific incorporation of optical probes into large recombinant proteins. The strategy is the combination of two existing techniques, expressed protein ligation (EPL) and in vivo amino acid replacement of tryptophans with tryptophan
