... A comparable study of thermal stability of formate dehydrogenases from microorganisms and plants. ... C1, the methanol-utilizing yeast Candida boidinii , and plants Arabidopsis thaliana and Glycine max (soybean) was performed. ... The enzymes were irreversibly inactivated in one stage according to first-order reaction kinetics. The FDH from Pseudomonas sp.101 appeared as the most thermostable enzyme; its counterpart from Glycine max exhibited the lowest stability. ...
... Use of Ramachandran plot for increasing thermal stability of bacterial formate dehydrogenase. ... The His263Gly mutation caused FDH destabilization and a 1.3-fold increase in the monomolecular inactivation rate constant. The replacements Ala191Gly and Asn234Gly had no significant effect on the stability. ... The stabilizing effect of the Tyr144Gly mutation was shown to be additive when introduced into the previously obtained mutant FDH with enhanced thermal stability. ...
... The FDH from Pseudomonas sp. 101 appeared as the most thermostable enzyme; its counterpart from Glycine max exhibited the lowest stability. The enzymes from Moraxella sp. ... The temperature dependence of the inactivation rate constant of A. thaliana FDH was studied. ... 101 FDH at 62ђC. Accounting for the fact that the inactivation rate constant for P-FDH increased 10-fold as the temperature went up by 3ђC [17], the difference between the thermal stabilities of these two enzymes at the same No. ...
