Deskripsi

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.
