A K m of 5.5 μM was obtained for 2 (More information) Severe thiamin deficiency leads to beriberi, a disease that affects multiple organ systems, including the central and peripheral nervous systems. TPP acts as coenzyme in oxidative decarboxylation and transketolase reactions. Thiamine pyrophosphate. Primary Functions of Thiamine in Cell Culture Systems: Thiamine is a required nutrient that is taken up by cells via a carrier-mediated system that may be regulated by calmodulin.
