Inhibitors

Inhibitors Comment Organism Structure
K+ thermal stability of the pkBADH-NAD+ complex in the presence of K+ shows a complete loss of the ellipticity signal and highly cooperative thermal transitions in each thermogram in the presence of each K+ concentration tested. In all tested conditions, the thermal denaturation is irreversible Sus scrofa
NADH a mixed-type inhibitor of the enzyme. After NADH release, the enzyme cannot start a new catalytic cycle, possibly because of the catalytic residue protonation state Sus scrofa

Metals/Ions Comment Organism Structure
K+ required for binding of cofactor NAD+. K+ causes small changes in secondary and tertiary structures that influences the active site conformation, binding of K+ to the enzyme caused changes in the alpha-helix content of 4% and 12% in the presence of 25 mM and 100 mM K+, respectively Sus scrofa

More secondary and tertiary structure of pkBADH in presence or absence of NAD+, fluorescence quenching spectra of pkBADH titrated with variable NAD+ concentrations in presence of potassium, overview. The deconvolution data analysis shows a 13% increase in the pkBADH helical structure, a decrease of 7% in beta-sheet content and 6% in turns content during the pkBADH-NAD+ complex formation Sus scrofa

47.2 59.9 thermal stability of the pkBADH-NAD+ complex in the presence of K+ shows a complete loss of the ellipticity signal and highly cooperative thermal transitions in each thermogram in the presence of each K+ concentration tested. In all tested conditions, the thermal denaturation is irreversible. The first derivative analysis from the pkBADH-NAD+ complex shows a peak with a (Tm)app value of 47.2°C, the addition of 25 mM K+ increased the (Tm)app to 59.9°C, while the addition of 50 mM or 100 mM K+ provokes changes in the (Tm)app to 55.9°C or 54.9°C, respectively. Binding of NAD+ to pkBADH causes a lower thermal stability of the enzyme Sus scrofa
