The guanineplus-cytosine content of the DNA was 44.1 +/-0.2 mol %. Glyoxylate was utilized as the only substrate and was stoichiometrically degraded to carbon dioxide, hydrogen, and glycolate. An acetyl-CoA and ADP-dependent glyoxylate converting enzyme activity, malic enzyme, and pyruvate synthase were found at activities sufficient for growth (>/= 0.25 U x mg protein- 1). These findings allow to design a new degradation pathway for glyoxylate: glyoxylate is condensed with acetyl-CoA to form malyl-CoA; the free energy of the thioester linkage in malyl-CoA is conserved by substrate level phosphorylation. Part of the electrons released during glyoxylate oxidation to CO2 reduce a small fraction of glyoxylate to glycolate. 2011-03-24T17:35:06Z Schink, Bernhard
