Along with folic acid, this vitamin is found in banana bags that are used to treat chronic alcoholics.
In Neurospora crassa, Ronald Breaker's lab discovered a riboswitch in the intron of the gene NMT1 that binds a derivative of this compound, preventing mRNA transcription. The cofactor derived from this compound forms an alphaÂ­hydroxyalkyl intermediate in its mechanism, which subsequently forms another intermediate where that cofactor is doubleÂ­bonded to its substrate. This compound contains an active5Â­membered nitrogenÂ­ and sulfurÂ­containing ring that has carbenoid properties and can be used as a catalyst in the benzoin condensation. That cofactor is necessary for (*) transketolase and the first step of the pyruvate dehydrogenase complex, and is formed by attaching pyrophosphate to this compound. Along with folic acid, this vitamin is found in banana bags that are used to treat chronic alcoholics. This vitamin's deficiency leads to a Wernicke's encephalopathy named for Korsakoff. For 10 points, name this vitamin whose deficiency also causes beriÂ­beri.
