摘要:
AbstractEquilibrium constants for the binding of azide to ferri‐cytochromecat temperature range‐of 305–325 K were determined at pH =7 by using1H double resonance method. Thermodynamic values (ΔH°=‐34.5 kJ/mol,ΔS°=‐100 J/mol) were obtained from van't Hoff's relation and were compared with those for azide binding to other ferric hemeproteins. The reason of lower affinity of cytochromecfor azide
