A PHGDH inhibitor reveals coordination of serine synthesis and one-carbon unit fate
Serine is a both a proteinogenic amino acid and the source of one-carbon units essential for de novo purine and deoxythymidine synthesis. In the canonical glucose-derived serine synthesis pathway, Homo sapiens phosphoglycerate dehydrogenase (PHGDH) catalyzes the first, ratelimiting step. Genetic lo...
