The structural properties of Mycobacterium tuberculosis (Mtb) ribonucleotide reductase R2 protein were studied under varying pH and temperature conditions by circular dichroism (CD) spectroscopy as well as dynamic light scattering (DLS). Under physiological conditions this protein has a high α-helical content, similar to the corresponding protein from other species, e.g. mouse. Decreasing the pH induced...
Yeast hexokinase has been poorly characterized in regard with its stability. In the present study, various spectroscopic techniques were employed to investigate thermal stability of the monomeric form of yeast hexokinase B (YHB). The enzyme underwent a conformational transition with a T m of about 41.9 °C. The structural transition proved to be significantly reversible below 55 °C and irreversible...
