Protein Domain : Citrate lyase beta subunit-like IPR011206

Type	Family
Description	This entry represents a group of proteins belonging to the HpcH/HpaI aldolase family. Proteins in this entry include citrate lyase subunit beta, malyl-CoA lyase and (3S)-malyl-CoA thioesterase. This entry also includes beta-methylmalyl-CoA lyase (rrnAC0690) from Haloarcula marismortui. Citrate lyase catalyses the magnesium-dependent cleavage of citrate to acetate and oxaloacetate. In bacteria, this reaction is involved in citrate fermentation. The bacterial enzyme is composed of three subunits: alpha, beta and gamma. Catalytic activity resides on the alpha- and beta-subunits, whereas the gamma-subunit serves as an acyl carrier protein (ACP) [ ]. Mammalian citrate lyase beta proteins display similarity to the bacterial enzymes [].Malyl-CoA lyase catalyses the reversible condensation of glyoxylate and acetyl-CoA to L-malyl-CoA and the reversible condensation of glyoxylate and propionyl-CoA to beta-methylmalyl-CoA [ ]. (3S)-malyl-CoA thioesterase catalyses the hydrolysis of (3S)-malyl-CoA to (3S)-malate and free CoA [ ]. Haloarcula marismortui beta-methylmalyl-CoA lyase may be involved in the methylaspartate cycle [ ]. It catalyses the reversible cleavage of beta-methylmalyl-CoA to propionyl-CoA and glyoxylate, as well as the reversible cleavage of (S)-malyl-CoA to acetyl-CoA and glyoxylate with some (S)-malyl-CoA thioesterase activity [].
