From Amino Acids to α-Keto Acids via β-Elimination and Transamination Initiates a Pathway to Prebiotic Reaction Networks. [PDF]

open access: yesAngew Chem Int Ed Engl
A reaction starting from two amino acids, phosphoserine and Gly, reveals a pathway to the α‐keto acid building blocks pyruvate and glyoxylate, key components of a plausible early metabolic system. A one‐pot β‐elimination and transamination sequence also initiates a cascade of protometabolic transformations that provide crucial insights into the ...
