Remarkable success in engineering novel efficient biomarkers based on fluorescent and photoactive proteins provokes a question of whether computational modeling their properties can contribute to this important field. In Feature Article, we analyze selected papers devoted computer simulations three types systems: the green protein its derivatives, flavin-binding proteins, phytochrome domains. The main emphasis is structures, optical spectra, chemical reactions chromophore-containing pockets. Quantum chemistry, quantum mechanics/molecular mechanics, molecular dynamics methods are effective tools these simulations. We highlight both stories persisting challenges, discussing ways elevating theoretical approaches level testable predictions.

Singlet oxygen (1O2) is a biologically relevant reactive species capable of efficiently reacting with cellular constituents. The resulting oxidatively generated damage to nucleic acids, membrane unsaturated lipids, and protein components has been shown be implicated in several diseases, including arthritis, cataracts, skin cancer. may endogenously produced, among various possibilities, by myeloperoxidase, an enzyme inflammation processes, also the UVA component solar radiation through photosensitization reactions. Emphasis placed this Review on description main oxidation reactions initiated 1O2 modifications within key targets, guanine for targeted amino acids. Most these give rise peroxides dioxetanes, whose formation rationalized terms [4+2] cycloaddition 1,2-cycloaddition dienes + olefins, respectively. use [18O]-labeled thermolabile endoperoxides as source applied study mechanistic aspects preferential targets biological systems. A major topic deals search molecular signature biomolecules cells. It anticipated that labeled association sensitive mass spectrometric methods should constitute powerful tools purpose.

Light has received increased attention for various chemical reactions but also in combination with biocatalytic reactions. Because currently only a few enzymatic are known, which per se require light, most transformations involving light and biocatalyst exploit either providing the cosubstrate or cofactor an appropriate redox state biotransformation. In selected cases, promiscuous activity of known enzymes presence could be induced. other approaches, light-induced have been combined step, were linear cascade. Finally, switchable moiety investigated to turn off/on tune actual reaction. This Review gives overview approaches using biocatalysis.

Optogenetics combines light and genetics to enable precise control of living cells, tissues, organisms with tailored functions. has the advantages noninvasiveness, rapid responsiveness, tunable reversibility, superior spatiotemporal resolution. Following initial discovery microbial opsins as light-actuated ion channels, a plethora naturally occurring or engineered photoreceptors photosensitive domains that respond at varying wavelengths ushered in next chapter optogenetics. Through protein engineering synthetic biology approaches, genetically encoded photoswitches can be modularly into scaffolds host cells myriad biological processes, well behavioral disease intervention vivo. Here, we summarize these optogenetic tools on basis their fundamental photochemical properties better inform chemical design principles. We also highlight exemplary applications opsin-free optogenetics dissecting cellular physiology (designated "optophysiology") describe current progress, future trends, wireless optogenetics, which enables remote interrogation physiological processes minimal invasiveness. This review is anticipated spark novel thoughts next-generation devices promise accelerate both basic translational studies.

Abstract Light‐based technique, including optical imaging and photoregulation, has become one of the most important tools for both fundamental research clinical practice, such as cell signal sensing, cancer diagnosis, tissue engineering, drug delivery, visual regulation, neuromodulation, disease treatment. In particular, low energy near‐infrared (NIR, 700–1700 nm) light possesses lower phototoxicity higher penetration depth in living systems compared with ultraviolet/visible light, making it a promising tool vivo applications. Currently, NIR light‐based photoregulation strategies have offered possibility to real‐time sense and/or modulate specific cellular events deep tissues subcellular accuracy. Herein, recent progress respect monitoring modulating spatiotemporal dynamics functions are summarized. applications techniques theranostics, regenerative medicine, neuroscience systematically introduced discussed. addition, challenges prospects sensing regulating comprehensively
