Histidine Ammonia Lyase Mechanism

The video tutorial explores the catabolism of histidine, focusing on the unique mechanism catalyzed by histidine ammonia lyase. It highlights the role of the coenzyme methyl Ladin Imidazol, detailing the mechanistic steps including ligation, deprotonation, and beta elimination. The process involves the formation of an alkene and the regeneration of the cofactor, emphasizing the enzyme's role as a biological catalyst. The tutorial concludes with a recap and a discussion on the E1 mechanism involved.
