... 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. ...
