4-(trimethylamino)butanoate + NADH + 2 H(+) => 4-(trimethylamino)butanal + NAD(+) + H2O
4-(trimethylamino)butanoate + nadh + 2 h(+) => 4-(trimethylamino)butanal + nad(+) + h2o
4-(trimethylamino)butanoate + NADH + 2 H(+) => 4-(trimethylamino)butanal + NAD(+) + H2O
4-(trimethylamino)butanoate + nadh + 2 h(+) => 4-(trimethylamino)butanal + nad(+) + h2o
