Ancestral Protein-Based Lighting.

ABSTRACT: Protein-optoelectronics is a paradigm toward eco-designed and sustainable technologies. The challenge is, however, how to preserve the native activity of proteins upon device fabrication/operation in non-native environments (solvents, organic/inorganic interfaces, and working temperatures/irradiations). Herein, a new vision to identify and design ancestral-like fluorescent proteins (FPs) is proposed. Using ancestral sequence reconstruction (ASR) out of a large dataset (221) of the best modern FPs suitable for photon down-conversion in bio-hybrid light-emitting diodes (Bio-HLEDs) a historical-genetic reconstruction (family tree) was obtained, identifying a possible common ancestral FP. This computationally designed protein is produced in bacteria, featuring outstanding photoluminescence qua
