Additional information

The gene is annotated in KEGG as an ortholog of malate dehydrogenase EC 1.1.1.37. It is marked but is marked as “uncharacterized oxidoreductase” (EC 1.1.1.-) in Swiss-Prot. In MetaCyc it is marked as “similar to malate dehydrogenase”. As the paper by Mekjian et al. PubMed suggests this gene is more likely to be involved in the glucuronate pathway (for which EC 1.1.1.37 is not a member), no literature/experimental evidence supporting the annotation is available.
