WebJul 13, 2024 · The glyoxylate cycle is basically a shunt in the TCA cycle, with which it shares many metabolic enzymes, including malate dehydrogenase, citrate synthase, and aconitase . The two decarboxylation steps involve isocitrate dehydrogenase and α-ketoglutarate dehydrogenase in the TCA cycle and are essentially excluded from the glyoxylate cycle. WebNov 17, 2024 · Introduction. The glyoxylate cycle, also known as glyoxylate shunt (GS), was identified by Kornberg and Krebs in 1957, explaining how organisms could grow on acetate as the sole carbon source (Kornberg and Krebs, 1957).For substrates degraded exclusively to acetyl moieties (e.g., acetate, fatty acids, and ketogenic amino acids), this pathway …
