Directed evolution of a TNA polymerase identifies independent paths to fidelity and catalysis - Nature Communications

| Nature Verified
Abstract Directed evolution facilitates functional adaptations through stepwise changes in sequence that alter protein structure. While most campaigns yield solutions that maintain the framework of a rigid protein architecture, a few have produced enzymes with more notable structural differences. One example is a polymerase that was evolved to synthesize threose nucleic acid (TNA) with near-natural activity.

50 years after the Fall of Saigon, we are reliving history in Gaza

Today marks 50 years since the Fall of Saigon – the day the Vietnam War officially ended and the country was declared “reunified.” But for many, it marked the beginning of something far more terrifying: the loss of home, the collapse of a way of life, and the terrifying unknown of what came next. Our father was one of the hundreds of thousands who fled, escaping persecution.

Directed evolution of a highly efficient TNA polymerase achieved by homologous recombination - Nature Catalysis

By Victoria A. Maola, Mohammad Hajjar, Joy Lee, Manuel Holguin, Riley N Quijano, Katherine Ho, Jenny Medina Verified, Nicholas Chim, Kalvin K. Nguyen
| Nature Verified
Abstract Reprogramming DNA polymerases to synthesize xeno-nucleic acids (XNAs) is an important challenge that tests current enzyme engineering tools. Here we describe an evolutionary campaign aimed at generating an XNA polymerase that can efficiently make α-l-threofuranosyl nucleic acid (TNA)—an artificial genetic polymer that is recalcitrant to nucleases and resistant to acid-mediated degradation.
