The photorespiratory pathway (black) short circuited by the bacterial glycolate pathway (blue) and alternatively by the intracholorplastic glycolate oxidation pathway (red). Enzymes overexpressed for the full functioning of these pathways are highlighted in bold. 1, Rubisco; 2, 2-PG phosphatase; 3 and 17, GO; 4 and 18, catalase; 5, Glu-glyoxylate aminotransferase; 6, Gly decarboxylase; 7, Ser hydroxymethyl transferase; 8, Ser-glyoxylate aminotransferase; 9 and 10, hydroxypyruvate reductase; 11, glycerate kinase; 12, Gln synthetase; 13, Gln-oxoglutarate aminotransferase; 14, GlcDH; 15, glyoxylate carboligase; 16, tartronate semialdehyde reductase; 19, malate synthase; 20, NADP-malic enzyme; 21, pyruvate dehydrogenase. THF, Tetrahydrofolate; 5,10-CH2-THF, 5,10-methylenetetrahydrofolate. Modified from Maurino and Peterhansel (2010).
