SDS-PAGE of expressed (a) and purified (b) Pol AFP IV and its TH activity and ice morphology (c). a M protein size marker, lane 1 lysates of uninduced bacteria, lane 2 lysates of bacteria induced with IPTG and lanes 3 and 4 soluble fraction and insoluble fractions of total protein from the induced bacteria, respectively. b M protein size marker, lane 1 elution fraction 1, and lane 2 elution fraction 2. Arrows indicate Pol AFP IV. c Antifreeze activity of recombinant Pol AFP IV. The ice morphology of the Pol AFP IV solution was examined using a nanoliter osmometer under a light microscope
