Description

Filipe Fusco and co-authors show that the first few letters of a gene's message can decide how much protein a factory cell makes. Recombinant proteins, many of them medicines, are chronically underproduced, and engineers usually blame the bioreactor or the purification train. Their paper, published in 2023, instead inspects the start of the messenger RNA in bacteria making a detoxified pneumolysin, a vaccine candidate protein.

Clones with and without a small purification tag at the protein's head were grown in ten-liter reactors, alongside a version of the gene whose opening letters were silently rewritten. The tag's presence raised output at least one and a half times, and computer folding of the message explained why: its opening formed a structure the ribosome opens easily. The rewritten version folded tighter and produced less. The authors plead for molecular design to join process design in yield work.
