WebJan 12, 2024 · While nuclear localization of PDH has been reported in other systems (Chueh et al., 2011, Sutendra et al., 2014), nuclear localization of a TCA cycle enzyme such as citrate synthase is an unexpected finding and led us to investigate the 2-cell embryo localization status of all TCA cycle enzyme isoforms that normally function in the mitochondrion. WebAug 1, 2024 · First, mouse prostate organoids exhibit a TCA cycle than is not only comprised of oxaloacetate-citrate. Second, glutamine is a major nutrient fueling the truncated TCA cycle at the αKG entry point—a well-known pathway that allows mitochondrial respiration. Third, glutamine could also fuel citrate production through reductive carboxylation.

Citrate is the TCA cycle intermediate where 2‐carbon units enter the cycle. WebDec 17, 2024 · Step 2. In step two, citrate loses one water molecule and gains another as citrate is converted into its isomer, isocitrate. Step 3. In step three, isocitrate is oxidized, producing a five-carbon molecule, α-ketoglutarate, together with a molecule of CO 2 and two electrons, which reduce NAD + to NADH. the shaub group
