Effect of the half wave potential and change of some viologens on the rate of conversion of crotonic acid into butyric acid by enoate reductase
article
The rate of the bio-electrochemical conversion of crotonic acid into butyric acid by enoate reductase is dependent on the type of viologen used. This illustrates that the reaction between enzyme and mediator, rather than the reaction between enzyme and crotonic acid, is rate limiting. Thus for bio-electrochemical conversion of enoates into saturated chiral acids immobilization of enoate reductase is beneficial from a kinetic point of view. The highest rate constant (k'=7.0×106 M-1.s-1) was measured using mono-N-(aminopropyl) viologen. © 1992 Science & Technology Letters.
