Message definition (Thiamine pyrophosphate ) ==Reaction mechanisms== In several reactions, including that of pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase, and transketolase, TPP catalyses the reversible decarboxylation reaction (aka cleavage of a substrate compound at a carbon-carbon bond connecting a [[carbonyl group]] to an adjacent reactive group—usually a [[carboxylic acid]] or an [[Alcohol (chemistry)|alcohol]]). It achieves this in four basic steps:
反応のメカニズム
ピルビン酸デヒドロゲナーゼ、α-ケトグルタル酸デヒドロゲナーゼ、トランスケトラーゼなどのいくつかの反応において、TPPは可逆的な脱炭酸反応(基質化合物の、カルボニル基 と隣接する反応性基-通常はカルボン酸 またはアルコール -をつなぐ炭素-炭素結合の開裂)を触媒する。これは4つの基本的なステップで達成される:
