Enzymatic DNA synthesis could deliver longer, purer and greener oligonucleotides than phosphoramidite chemistry. It requires an enzyme that is template-independent, adds exactly one nucleotide per cycle, accepts 3 -reversible terminators and withstands process conditions. This translational, KU Leuven-funded project continues the development of a recently discovered engineered hyperthermophilic polymerase with template-independent activity. You will improve it through directed evolution and structure-guided design. Your targets are terminator acceptance, coupling efficiency and control over stepwise addition, and you will benchmark variants in complete synthesis cycles.

The Pinheiro group has a well-established pipeline for engineering DNA polymerases with expanded substrate specificity. It covers automated multi-site library construction, selection platforms such as bacterial cell display, NGS-based analysis of selection outputs, and structural and computational analysis of evolved variants. You will design selection conditions, interpret sequencing data quantitatively, and characterise hits biochemically, including kinetic analysis of nucleotide incorporation. You will also help build an industrial network to license or co-develop the enzyme and ancillary technologies.
