PiL[D24]
Multi-Component SwitchPiL[D24] is an engineered mammalian pyruvate kinase M2 (PKM2) photoswitch containing an internal insertion of the Avena sativa LOV2 light-sensing domain at position D24. Illumination preserves the LOV2 photoreaction and allosterically modulates PKM2 behavior, increasing pyruvate kinase activity and cellular labeling of pyruvate from glucose.
