Thermal denaturation profiles of human H2S-synthesizing enzymes. Thermal denaturation profiles of recombinant human cystathionine β-synthase (CBS, top panel), cystathionine γ-lyase (CSE, middle panel) and 3-mercaptopyruvate sulfurtransferase (MST, bottom panel), obtained by differential scanning fluorimetry (DSF, short dashed points, curves marked with ‘a’) or Far-UV circular dichroism spectropolarimetry (CD, hollow circles, curves marked with ‘b’).
