Webbnot exactly, the initial velocity would be determined by drawing a tangent to the beginning of the "burst phase" (not the tangent they show in the illustration, that's a regression line from the linear part of the reaction). once the reaction is linear you are past the initial velocity. Thank you for the links, they seem very usefull. Webb, defined as the velocity of the reaction immediately after the enzyme steady state has been achieved. Since the determination of the properties of an enzyme depend upon various applications of the MichaelisMenten equation- , it is critically important that the initial velocity of an enzyme catalyzed reaction is accurately measured.
