Real-time observation of tetrapyrrole binding to an engineered bacterial phytochrome
Near-infrared fluorescent proteins engineered from bacterial phytochromes are important for deep-tissue imaging in vivo, but the mechanism through which they bind to chromophores is not fully understood. Here the authors structurally analyze biliverdin binding to miRFP proteins using time-resolved s...

| Résumé: | Near-infrared fluorescent proteins engineered from bacterial phytochromes are important for deep-tissue imaging in vivo, but the mechanism through which they bind to chromophores is not fully understood. Here the authors structurally analyze biliverdin binding to miRFP proteins using time-resolved stimulated Raman spectroscopy and quantum mechanical/molecular mechanics calculations. |
