Dead end inhibition
Webvelocity data. For the calculation of the inhibition constants in studies of products and dead end inhibitors, slopes and intercepts of the primary double reciprocal plots were plotted … Webhuman ADH family. Initial velocity, product inhibition, and dead-end inhibition experiments were performed with the recombinant human class IV ADH to elucidate kinetic mechanism with all-trans-retinol and all-trans-retinal as natural substrates. Fluorescence quenching was titrated in formation of the binary and abortive ternary enzyme complexes.
