COMMENTARY 
LITERATURE
40 - 60
purified recombinant enzyme, pH 8.0, reasonably stable, maintaining 60% activity after 4 h at 40, and 50% activity after 30 min at 50°C, and almost fully inactivated at 60°C after 1 h

additional information
the enzyme from a psychrophilic bacterium, MvNeuB, is less stable at higher temperature and has a high catalytic activity at lower temperature compared to mesophilic counterparts. MvNeuB is a typical cold adapted enzyme

additional information
the wild-type apoenzyme has a higher melting temperature of 42.6°C compared to the mutant G272Term apoenzyme with 36.5°C. Unlike the wild-type enzyme, the melting temperature of mutant G272Term in the presence of Mn2+ remains consistent and is not influenced by the addition of different ligand combinations. The melting temperature of wild-type NmeNANAS increases slightly in the presence of Mn2+
