A one-pot enzymatic reaction sequence for the synthesis of optically pure d-glyceraldehyde 3-phosphate (d-GAP) and l-glycerol 3-phosphate (sn-G3P) was designed using fructose-bisphosphate aldolase from rabbit muscle (RAMA), sn-glycerol 3-phosphate dehydrogenase (sn-G3PDH) and formate dehydrogenase from Candida boidinii (FDH). The reaction sequence significantly improves the aldol cleavage of d-fructose 1,6-bisphosphate (d-F16BP) catalyzed by RAMA and yields 100% conversion of d-F16BP by overcoming thermodynamic limitation. The degradation kinetics of d-GAP under reaction conditions was investigated and a reaction kinetics model defining the entire cascade was developed. Validation of the model shows 98.5% correlation between experimental data and numerically simulated data matrices. The evaluation of different types of reactor was performed by combining the reaction kinetics model, mass balances and kinetics of the non-enzymatic degradation of d-GAP. Batch-wise operation in a stirred tank reactor (STR) is the most convenient procedure for the one-pot enzymatic syntheses of d-GAP and sn-G3P. The separation of the two products d-GAP and sn-G3P has been achieved using polyethylenimine (PEI)-cellulose TLC.

The poor reactivity of insoluble phosphates, such as apatite-group minerals, has been a long-appreciated obstacle for proposed models of prebiotic organophosphate formation. This obstacle presents a significant challenge to the nascent development of an RNA world and other models for the origins of life on Earth. Herein, we demonstrate that a scenario based on the formation of a urea/ammonium formate/water (UAFW) eutectic solution leads to an increase in phosphorylation when compared to urea alone for phosphate sources of varying solubility. In addition, under evaporative conditions and in the presence of MgSO4, the UAFW eutectic mobilizes the phosphate sequestered in water-insoluble hydroxyapatite, giving rise to a marked increase in phosphorylation. These results suggest that the prebiotic concentrations of urea in a geologically plausible evaporitic environment could solve the problem of organic phosphorylation on a prebiotic Earth.
