Lysine 6-dehydrogenase (, ''L-lysine epsilon-dehydrogenase'', ''L-lysine 6-dehydrogenase'', ''LysDH'') is an enzyme with system name ''L-lysine:NAD+ 6-oxidoreductase (deaminating)''. This enzyme catalyses the following chemical reaction : L-lysine + NAD+ (S)-2,3,4,5-tetrahydropyridine-2-carboxylate + NADH + H+ + NH3 (overall reaction) : (1a) L-lysine + NAD+ + H2O (S)-2-amino-6-oxohexanoate + NADH + H+ + NH3 : (1b) (S)-2-amino-6-oxohexanoate (S)-2,3,4,5-tetrahydropyridine-2-carboxylate + H2O (spontaneous) The enzyme is highly specific for L-lysine as substrate, although S-(2-aminoethyl)-L-cysteine can act as a substrate, but more slowly. == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Lysine 6-dehydrogenase」の詳細全文を読む スポンサード リンク
