Abstract
Aldo-keto reductases tighten coenzyme binding by forming a hydrogen bond across the pyrophosphate group of NAD(P)(H). Mutation of the hydrogen bonding anchor Lys24 in Candida tenuis xylose reductase prevents fastening of the “safety belt” around NAD(H). The loosened NAD(H) binding leads to increased turnover numbers (kcat) for reductions of bulky-bulky ketones at constant substrate and coenzyme affinities (i.e. Km Ketone, Km NADH).
