Metabolite Identification
Common Name2-Methyl-1-hydroxypropyl-ThPP
Description2-Methyl-1-hydroxypropyl-ThPP is an intermediate in valine, leucine and isoleucine degradation(KEGG ID C15976). It is the second to last step in the synthesis of isobutyryl-CoA and is converted from 3-methyl-2-oxobutanoate via the enzyme 2-oxoisovalerate dehydrogenase [EC:1.2.4.4]. It is then converted to S-(2-methylpropanoyl)-dihydrolipoamide-E via the enzyme 2-oxoisovalerate dehydrogenase [EC:1.2.4.4]].
