Using a fluorescent NBD amino acid, new protease substrates were developed that are attractive because of the excellent chemical stability and long wavelength of excitation (480 nm) of the NBD fluorophore. The fluorescent peptides are synthesized by Fmoc solid-phase peptide synthesis. An example peptide was efficiently immobilized onto a microarray surface using click chemistry, and its proteolysis was monitored by fluorescence imaging. Excellent site specificity was achieved for the protease. Fluorescent peptides are also used to monitor the conjugation efficiency onto a surface using a standard microarray scanner.

Tracking a bug's life: Peptidoglycan (PG) of diverse bacteria is labeled by exploiting the tolerance of cells for incorporating different non‐natural D‐amino acids. These nontoxic D‐amino acids preferably label the sites of active PG synthesis, thereby enabling fine spatiotemporal tracking of cell‐wall dynamics in phylogenetically and morphologically diverse bacteria.

An unnatural amino acid comprising a fluorescent moiety is site-specifically incorporated into a protein through the use of an O-tRNA/O-RS pair which is orthogonal to the tRNAs and aminoacyl synthetases of a translation system, thereby allowing the protein to be analyzed.
