Biochem/physiol Actions

N-Acetyl-L-tryptophanamide (NATA) is an N-terminal and C-terminal blocked analogue of L-tryptophan. L-tryptophan, NATA and NATA-tyr molecules have intrinsic fluorescence which makes them useful in studies involving fluorescence and flurosence enhancement.

Cellular transport machinery, such as channels and pumps, is working against the background of unassisted material transport through membranes. The permeation of a blocked tryptophan through a 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) membrane is investigated to probe unassisted or physical transport. The transport

We present a label-free detection of protein interaction between beta-galactosidase from Escherichia coli (Ecbeta-Gal) and monoclonal anti-Ecbeta-Gal using deep UV laser-based fluorescence lifetime microscopy. The native fluorescence from intrinsic tryptophan emission was observed after one-photon excitation at 266 nm. Applying

The conformational isomerization dynamics of N-acetyl tryptophan methyl amide (NATMA) and N-acetyl tryptophan amide (NATA) have been studied using the methods of IR-UV hole-filling spectroscopy (HFS) and IR-induced population transfer spectroscopy (IR-PTS), which were developed for this purpose. Single conformations

Sugars are known to stabilize proteins. This study addresses questions of the nature of sugar and proteins incorporated in solid sugar films. Infrared (IR) and Raman spectroscopy was used to examine trehalose and sucrose films and glycerol/water solvent. Proteins and
