The ORF YNL274c (GOR1) codes for glyoxylate reductase in Saccharomyces cerevisiae.
The enzyme glyoxylate reductase reversibly reduces glyoxylate to glycolate, or alternatively hydroxypyruvate to D-glycerate, using either NADPH or NADH as a co-factor. The enzyme has multiple metabolic roles in different organisms. In this paper we show that GOR1 (ORF YNL274c) encodes a glyoxylate reductase and not a hydroxyisocaproate dehydrogenase in Saccharomyces cerevisiae, even though it also has minor activity on alpha-ketoisocaproate. In addition, we show that deletion of the glyoxylate reductase-encoding gene leads to higher biomass concentration after diauxic shift.
