title: Mechanism of NADH transfer between alcohol dehydrogenase and glyceraldehyde-3-phosphate dehydrogenase.
abstract: Steady-state and transient-state kinetic experiments have been performed to test the proposal that there is a direct (channelled) transfer of NADH from glyceraldehyde-3-phosphate dehydrogenase to alcohol dehydrogenase. The results lend no support to this proposal, but can be best explained in terms of a free-diffusion mechanism for NADH transfer between the two enzymes.
