SpletThe most selective enzyme inhibitors generally fall into the class known as mechanism-based inactivators. These are substrates for the target enzyme and are converted to reactive species that modify groups in the active site and cause loss of function (Ortiz de Montellano and Correia 1983; Rando 1984; Silverman 1988; Walsh 1979).As the term … SpletA typical enzyme molecule can convert 1,000 substrate molecules per second. The rate of an enzymatic reaction increases with increased substrate concentration, reaching maximum velocity when all active sites of the enzyme molecules are engaged. The enzyme is then said to be saturated, the rate of the reaction being determined by the speed at ... SpletAffiliations. 1 a H. E. J.
