Laconic is a genetically-encoded biosensor that detects lactate in the physiological range. The sensor was based on LldR, a bacterial transcription regulator that consists of a lactate-binding/regulatory domain and a DNA-binding domain. Laconic consists of a N-terminal mTFP, followed by the LldR flanked by linkers, and finally a C-terminal Venus.
