Regulation Summary Diagram: ?

Component of: 2-oxoglutarate dehydrogenase complex (summary available)

Subunit composition of 2-oxoglutarate decarboxylase, thiamine-requiring = [SucA]12
         subunit of E1(0) component of 2-oxoglutarate dehydrogenase = SucA

Summary:
E. coli SucA is responsible for the 2-oxoglutarate decarboxylase activity of the 2-oxoglutarate dehydrogenase multienzyme complex (OGDHC) that catalyzes the conversion of 2-oxoglutarate (2-ketoglutarate) to succinyl-CoA and CO2, with the production of NADH (see 2-oxoglutarate decarboxylation to succinyl-CoA).

The OGDHC is a member of the 2-oxo acid dehydrogenase family [Bunik08]. Members of this family contain multiple copies of three enzymatic components: 2-oxoglutarate decarboxylase (E1), lipoamide acyltransferase (E2) and lipoamide dehydrogenase (E3). In most Gram-positive bacteria and in mitochondria the E1 component is a heterodimer composed of two subunits, while in most (but not all) Gram-negative bacteria it is made up of a single type of subunit. In both cases multiple copies of the E1 component along with multiple copies of the E3 component are assembled around an E2 core of 24 subunits with octahedral symmetry, or 60 subunits with eicosahedral symmetry (depending on which complex and species) [Reed01]. In E. coli the E3 component is shared with the pyruvate dehydrogenase and glycine cleavage multi-enzyme complexes. E1 and E2 differ slightly for the 2-oxoglutarate and pyruvate dehydrogenase complexes, and are designated (o) and (p) to distinguish them.

The E. coli OGDHC contains 12 units of the E1(o) component 2-oxoglutarate decarboxylase, thiamine-requiring encoded by sucA, 24 units of the E2(o) comoponent dihydrolipoyltranssuccinylase encoded by sucB, and 2 units of the E3 component lipoamide dehydrogenase encoded by lpd. The 24 E2(o) units form the octahedral core of the complex. They contain lipoyllysine and binding sites for dimers of the E1(o) and E3 subunits. Electron cryotomography showed that they are flexibly tethered to the E2 core [Murphy05].

During the OGDHC reaction cycle, 2-oxoglutarate is bound and decarboxylated by SucA, a thiamin-diphosphate cofactor containing enzyme. The crystal structure of a truncated, apo form of SucA lacking the N-terminal 77 residues has been determined at 2.6 Å resolution. The structure of the holo form with thiamin diphoisphate and Mg2+ was determined at 3.5 Å resolution. The truncated form retained decarboxylase activity but did not assemble with E2(o) into an OGDH complex. Data also suggested the presence of an AMP binding site [Frank07]. An oxygen-dependent thiamin free radical was demonstrated in the OGDHC, which was generated by a side reaction with O2 [Frank08].

Studies of engineered SucA prepared by saturation mutagenesis of His260 and His298 suggested that His260 is required for substrate recognition, but His298 could be replaced by hydrophobic residues of similar size. Data also suggested that E2(o) has a role in specificity [Shim11].

REACTION: E1(o) + TPP = E1(o).TPP, E1(o).TPP + 2-oxoglutarate = E1(o).hydroxycarboxypropylTPP + CO(2), E1(o).hydroxycarboxypropylTPP + E2(o).lipoate(S2) = E1(o).TPP + E2(o).lipoate(SH)(S-succinyl) (see [Waskiewicz84, Steginsky85])

The sucA gene was cloned and sequenced in earlier work [Spencer82, Darlison84a] and regulation of sucABCD was studied [Park97, Cunningham98]. The sucAB and sucCD genes were shown to be mutually essential, with either pair sufficient to produce succinyl-CoA, but simultaneous deletion of sucAB and sucCD was not viable [Yu06d].
