[[ | [[https://www.uniprot.org/uniprot/DLDH_HUMAN DLDH_HUMAN]] Note=Defects in DLD are involved in the development of congenital infantile lactic acidosis. Defects in DLD are a cause of maple syrup urine disease (MSUD) [MIM:[https://omim.org/entry/248600 248600]]. MSUD is characterized by mental and physical retardation, feeding problems and a maple syrup odor to the urine. The keto acids of the branched-chain amino acids are present in the urine, resulting from a block in oxidative decarboxylation. [[https://www.uniprot.org/uniprot/ODB2_HUMAN ODB2_HUMAN]] Defects in DBT are the cause of maple syrup urine disease type 2 (MSUD2) [MIM:[https://omim.org/entry/248600 248600]]. MSUD is an autosomal recessive disorder characterized by mental and physical retardation, feeding problems, and a maple syrup odor to the urine.<ref>PMID:1847055</ref> <ref>PMID:9621512</ref> | ||

[[ | [[https://www.uniprot.org/uniprot/DLDH_HUMAN DLDH_HUMAN]] Lipoamide dehydrogenase is a component of the glycine cleavage system as well as of the alpha-ketoacid dehydrogenase complexes. Involved in the hyperactivation of spermatazoa during capacitation and in the spermatazoal acrosome reaction. [[https://www.uniprot.org/uniprot/ODB2_HUMAN ODB2_HUMAN]] 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). | ||
