EC 2.3.3.9

Accepted name: malate synthase

Reaction: acetyl-CoA + H2O + glyoxylate = (S)-malate + CoA

Other name(s): L-malate glyoxylate-lyase (CoA-acetylating); glyoxylate transacetylase; glyoxylate transacetase; glyoxylic transacetase; malate condensing enzyme; malate synthetase; malic synthetase; malic-condensing enzyme; acetyl-CoA:glyoxylate C-acetyltransferase (thioester-hydrolysing, carboxymethyl-forming)

Systematic name: acetyl-CoA:glyoxylate C-acetyltransferase [(S)-malate-forming]

Comments: The enzyme catalyses the irreversible condensation of acetyl-CoA with glyoxylate to form (S)-malate. Among other functions, the enzyme participates in the glyoxylate cycle, a modified version of the TCA cycle that bypasses steps that lead to a loss of CO2.
