"We find that #purine synthesis constitutes a bottleneck for metabolic expansion, which can be alleviated by non-autocatalytic phosphoryl coupling agents. Early phases of the expansion are enriched with #enzymes that are metal dependent and structurally symmetric, supporting models of early #biochemical #evolution. This expansion trajectory suggests distinct hypotheses regarding the tempo, mode and timing of metabolic pathway evolution"

Happy to share our just accepted #review on #multitarget approaches for the #synthesis of #purine and #pyrimidine derivatives. From the #prebiotic/#abiotic origin of life to new #green #chemistry strategies for #drugdiscovery.
