Abstract
There is a need for photochemical tools that allow precise control of protein structure and function with visible light. We focus here on the s-tetrazine moiety, which can be installed at a specific protein site via the reaction between dichlorotetrazine and two adjacent sulfhydryl groups. Tetrazine's compact size enables structural mimicry of native amino acid linkages, such as an intramolecular salt bridge or disulfide bond. In this study, we investigated tetrazine installation in three different proteins, where it was confirmed that the cross-linking reaction is highly efficient in aqueous conditions and site-specific when two cysteines are located proximally: the S-S distance was 4-10 Å. As shown in maltose binding protein, the tetrazine cross-linker can replace an interdomain salt bridge crucial for xenon binding and serve as a visible-light photoswitch to modulate 129Xe NMR contrast. This work highlights the ease of aqueous tetrazine bioconjugation and its applications for protein photoregulation.

Abstract
The bulk cell population response to a stimulus, be it a growth factor or a cytotoxic agent, neglects the cell-to-cell variability that can serve as a friend or as a foe in human biology. Biochemical variations among closely related cells furnish the basis for the adaptability of the immune system but also act as the root cause of resistance to chemotherapy by tumors. Consequently, the ability to probe for the presence of key biochemical variables at the single-cell level is now recognized to be of significant biological and biomedical impact. Chemical cytometry has emerged as an ultrasensitive single-cell platform with the flexibility to measure an array of cellular components, ranging from metabolite concentrations to enzyme activities. We briefly review the various chemical cytometry strategies, including recent advances in reporter design, probe and metabolite separation, and detection instrumentation. We also describe strategies for improving intracellular delivery, biochemical specificity, metabolic stability, and detection sensitivity of probes. Recent applications of these strategies to small molecules, lipids, proteins, and other analytes are discussed. Finally, we assess the current scope and limitations of chemical cytometry and discuss areas for future development to meet the needs of single-cell research.

Abstract
We report the chemical synthesis of the first photo-activatable protein antigen that can be used to study antigen-antibody interaction mediated responses in B cells. This strategy facilitated fine tuning of the caged protein antigen to optimize its bioactivity and photochemical properties. One optimal molecule, HEL-K96NPE, was totally inert to hen egg lysozyme (HEL)-specific B cells and could only restore its antigenicity upon photoactivation. Combined with real time live cell imaging, the utility of HEL-K96NPE was demonstrated as a proof of concept to quantify B cell synapse formation and calcium influx responses at the single cell level.

Abstract
Although peptide-based therapeutics are finding increasing application in the clinic, extensive structural modification is typically required to prevent their rapid degradation by proteases in the blood. We have evaluated the ability of erythrocytes to serve as reservoirs, protective shields (against proteases), and light-triggered launch pads for peptides. We designed lipidated peptides that are anchored to the surface of red blood cells, which furnishes a protease-resistant environment. A photocleavable moiety is inserted between the lipid anchor and the peptide backbone, thereby enabling light-triggered peptide release from erythrocytes. We have shown that a cell-permeable peptide, a hormone (melanocyte stimulating hormone), and a blood-clotting agent can be anchored to erythrocytes, protected from proteases, and photolytically released to create the desired biological effect.

Abstract
![]()
The proteasome, a validated anticancer
target, participates in
an array of biochemical activities, which range from the proteolysis
of defective proteins to antigen presentation. We report the preparation
of biochemically and photophysically distinct green, red, and far-red
real-time sensors designed to simultaneously monitor the proteasome’s
chymotrypsin-, trypsin-, and caspase-like activities, respectively.
These sensors were employed to assess the effect of simultaneous multiple
active site catalysis on the kinetic properties of the individual
subunits. Furthermore, we have found that the catalytic signature
of the proteasome varies depending on the source, cell type, and disease
state. Trypsin-like activity is more pronounced in yeast than in mammals,
whereas chymotrypsin-like activity is the only activity detectable
in B-cells (unlike other mammalian cells). Furthermore, chymotrypsin-like
activity is more prominent in transformed B cells relative to their
counterparts from healthy donors.

Abstract
Although the corrin ring of vitamin B12 is unable to efficiently absorb light beyond 550 nm, it is shown that commercially available fluorophores can be used as antennas to capture long-wavelength light to promote scission of the Co-C bond at wavelengths up to 800 nm. The ability to control the molecular properties of bioactive species with long visible and near-IR light has implications for drug delivery, nanotechnology, and the spatiotemporal control of cellular behavior.
