Abstract: The steady-state kinetics of CCOwas studied by spectrophotometry.It is indicated that there are both higher and lower affinity phases when CCOreacts with its substrate ferrocy-tochrome c.The catalytic reaction is regulated by the concentration of the substrate and has a character of single substrate multiphasic kinetics.
