CC -!- FUNCTION: Lipoamide dehydrogenase is a component of the glycine
CC cleavage system as well as an E3 component of three alpha-ketoacid
CC dehydrogenase complexes (pyruvate-, alpha-ketoglutarate-, and branched-
CC chain amino acid-dehydrogenase complex). The 2-oxoglutarate
CC dehydrogenase complex is mainly active in the mitochondrion. A fraction
CC of the 2-oxoglutarate dehydrogenase complex also localizes in the
CC nucleus and is required for lysine succinylation of histones:
CC associates with KAT2A on chromatin and provides succinyl-CoA to histone
CC succinyltransferase KAT2A. In monomeric form may have additional
CC moonlighting function as serine protease (By similarity). Involved in
CC the hyperactivation of spermatazoa during capacitation and in the
CC spermatazoal acrosome reaction (By similarity).
CC {ECO:0000250|UniProtKB:P09622, ECO:0000250|UniProtKB:Q811C4}.

CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000250|UniProtKB:P09622};
CC Note=Binds 1 FAD per subunit. {ECO:0000250|UniProtKB:P09622};
CC -!- SUBUNIT: Homodimer. Part of the multimeric pyruvate dehydrogenase
CC complex that contains multiple copies of pyruvate dehydrogenase
CC (subunits PDHA (PDHA1 or PDHA2) and PDHB, E1), dihydrolipoamide
CC acetyltransferase (DLAT, E2) and lipoamide dehydrogenase (DLD, E3).
CC These subunits are bound to an inner core composed of about 48 DLAT and
CC 12 PDHX molecules (by non covalent bonds). The 2-oxoglutarate
CC dehydrogenase complex is composed of OGDH (2-oxoglutarate
CC dehydrogenase; E1), DLST (dihydrolipoamide succinyltransferase; E2),
CC DLD (dihydrolipoamide dehydrogenase; E3) and the assembly factor KGD4
CC (By similarity). It contains multiple copies of the three enzymatic
CC components (E1, E2 and E3). In the nucleus, the 2-oxoglutarate
CC dehydrogenase complex associates with KAT2A. Interacts with PDHX.
CC {ECO:0000250|UniProtKB:O08749, ECO:0000250|UniProtKB:P09622}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC {ECO:0000250|UniProtKB:P09622}. Nucleus {ECO:0000250|UniProtKB:P09622}.
CC Cell projection, cilium, flagellum {ECO:0000250|UniProtKB:Q811C4}.
CC Cytoplasmic vesicle, secretory vesicle, acrosome
CC {ECO:0000250|UniProtKB:P09622}. Note=Mainly localizes in the
CC mitochondrion. A small fraction localizes to the nucleus, where the 2-
CC oxoglutarate dehydrogenase complex is required for histone
CC succinylation. {ECO:0000250|UniProtKB:P09622}.
CC -!- PTM: Tyrosine phosphorylated. {ECO:0000250|UniProtKB:Q811C4}.
CC -!- MISCELLANEOUS: The active site is a redox-active disulfide bond.
CC {ECO:0000250|UniProtKB:P09624}.
CC -!- SIMILARITY: Belongs to the class-I pyridine nucleotide-disulfide
CC oxidoreductase family. {ECO:0000305}.
