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