>cd00945 Aldolase_Class_I Class I aldolases. The class I aldolases use an active-site lysine which stablilzes a reaction intermediates via Schiff base formation, and have TIM beta/alpha barrel fold. The members of this family include 2-keto-3-deoxy-6-phosphogluconate (KDPG) and 2-keto-4-hydroxyglutarate (KHG) aldolases, transaldolase, dihydrodipicolinate synthase sub-family, Type I 3-dehydroquinate dehydratase, DeoC and DhnA proteins, and metal-independent fructose-1,6-bisphosphate aldolase. Although structurally similar, the class II aldolases use a different mechanism and are believed to have an independent evolutionary origin.
