>TIGR01019 sucCoAalpha succinyl-CoA synthetase, alpha subunit; InterPro: IPR005810 There are four different enzymes that share a similar catalytic mechanism which involves the phosphorylation by ATP (or GTP) of a specific histidine residue in the active site. These enzymes are: ATP citrate-lyase (4.1.3.8 from EC) , the primary enzyme responsible for the synthesis of cytosolic acetyl-CoA in many tissues, catalyzes the formation of acetyl-CoA and oxaloacetate from citrate and CoA with the concomitant hydrolysis of ATP to ADP and phosphate. ATP-citrate lyase is a tetramer of identical subunits; Succinyl-CoA ligase (GDP-forming) (6.2.1.4 from EC) is a mitochondrial enzyme that catalyzes the substrate level phosphorylation step of the tricarboxylic acid cycle: the formation of succinyl-CoA from succinate with a concomitant hydrolysis of GTP to GDP and phosphate. This enzyme is a dimer composed of an alpha and a beta subunits; Succinyl-CoA ligase (ADP-forming) (6.2.1.5 from EC) is a bacterial enzyme that during aerobic metabolism functions in the citric acid cycle, coupling the hydrolysis of succinyl-CoA to the synthesis of ATP. It can also function in the other direction for anabolic purposes. This enzyme is a tetramer composed of two alpha and two beta subunits; and Malate-CoA ligase (6.2.1.9 from EC) (malyl-CoA synthetase) , is a bacterial enzyme that forms malyl-CoA from malate and CoA with the concomitant hydrolysis of ATP to ADP and phosphate. Malate-CoA ligase is composed of two different subunits. This entry corresponds to two regions, a glycine-rich conserved region, located in the second half of ATP citrate lyase and in the alpha subunits of succinyl-CoA ligases and malate-CoA ligase; and the active site phosphorylated histidine residue, which is located some 50 residues to the C-terminal of the first region. ; GO: 0003824 catalytic activity, 0008152 metabolic process.
