Figure 1From: The Rhodococcus opacus TadD protein mediates triacylglycerol metabolism by regulating intracellular NAD(P)H poolsProposed model for the role of TadD in TAG metabolism in R. opacus PD630. Under high nitrogen conditions (depicted on the left) glyceraldehyde 3-phosphate is metabolized to 3-phosphoglycerate by the canonical glyceraldehyde 3-phosphate dehydrogenase GapA and the phosphoglycerate kinase Pgk yielding NADH and ATP. We propose that under nitrogen limiting conditions G3P is metabolized to 3-phosphoglycerate by the non-phosphorylating, NAD(P)+-dependent glyceraldehyde 3-phosphate dehydrogenase TadD yielding NAD(P)H, a key redox molecule in fatty acid metabolism.Back to article page
