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]].

Enzymes

General function:
Involved in catalytic activity
Specific function:
The branched-chain alpha-keto dehydrogenase complex catalyzes the overall conversion of alpha-keto acids to acyl-CoA and CO(2). It contains multiple copies of three enzymatic components: branched-chain alpha-keto acid decarboxylase (E1), lipoamide acyltransferase (E2) and lipoamide dehydrogenase (E3).
