Enzyme kinetics was studied to find out the reactionrate of enzyme against the substrate (starch) through theLineweaver–Burk plot on different concentrations of starch rangingfrom 0.1% to 1.2% at pH of 6 and temperature of 55◦C. The Michaelisconstant (Km) and maximum velocity of the reaction (Vmax) werecalculated according to the Michaelis–Menten equation
