1901por Rauch, Marine C. R., Gallou, Yann, Delorme, Léna, Paul, Caroline E., Arends, Isabel W. C. E., Hollmann, Frank“…Both direct electron transfer from the metal to the enzyme as well as mediated electron transfer is feasible, although the latter excels by higher reaction rates. The general applicability of this new chemoenzymatic reduction method is demonstrated, and current limitations are outlined.…”
