fluorescence intensity of enzyme decreases with increasing heat treatment time and the maximum fluorescence wavelength shifts slightly towards longer wavelength, 340-345 nm and 342-346 nm. The fluorescence intensity in 50% glycerol does not change significantly following heat treatment. The maximum fluorescence wavelength also shifts slightly, 337-340 nm and 339-340 nm |

wild-type and mutant PSP enzymes can undergo reversible thermal inactivation at 37°C, pH 8.0, with activity being restored or even increased with respect to the initial one upon subsequent cooling. The process can be repeated several times, with the same results achieved (up to 5 cycles). This effect can be explained by a shift in the equilibrium between the inactive open form of the enzyme and the active closed one upon variation of the incubation temperature, overview |
