Abstract excerpt
In roots of Arabidopsis (Arabidopsis thaliana), l-lactate is generated by the reduction of pyruvate via l-lactate dehydrogenase, but this enzyme does not efficiently catalyze the reverse reaction. Here, we identify the Arabidopsis glycolate oxidase (GOX) paralogs GOX1, GOX2, and GOX3 as putative l-lactate-metabolizing enzymes based on their homology to CYB2, the l-lactate cytochrome c oxidoreductase from the...
