WebJan 1, 2024 · Phosphoglycerate dehydrogenase (PHGDH), as the first rate-limiting enzyme of the SSP, catalyzes the conversion of 3-phosphoglycerate (3-PG) into 3-phosphohydroxypyruvate (3-PHP)9, 10, 11. Subsequently, 3-PHP is converted to serine via phosphoserine aminotransferase (PSAT) and phosphoserine phosphatase (PSPH)4.
