AI-Driven Precision for High-Yield Engineering The Challenge: Even with advanced genetic tools, protein expression often remains suboptimal due to weak or slow-acting regulatory elements. The Innovation: The team demonstrated a breakthrough Design-Build-Test workflow. By combining biophysical modeling with synthetic biology libraries, they engineered biosensors with vastly improved sensitivity and speed. Rational Design over Trial-and-Error: Instead of random mutations, we us

Abstract In modern bioengineering, multicopy gene constructs are essential for reaching high protein yields and metabolic flux. However, these systems often suffer from severe genetic instability due to recombination and evolutionary pressure. Our team’s latest research, published in NAR Genomics and Bioinformatics, introduces ChimeraUGEM: a sophisticated tool that leverages biophysical modeling to design genetically stable multicopy sequences. By optimizing the "coding-regul

Abstract Evolutionary instability is a persistent challenge in synthetic biology, often leading to the loss of heterologous gene expression over time. Here, we present STABLES, a gene fusion strategy that links a gene of interest (GOI) to an essential endogenous gene (EG), with a “leaky” stop codon in between. This ensures both selective pressure against deleterious mutations and the high expression of the GOI. By leveraging a machine learning framework, we predict optimal GO

Abstract Plasmids constitute a key tool in synthetic biology, providing a versatile framework for various research and industrial ventures. An essential determinant of plasmid functionality is its copy number, impacting both protein production rates and host cell metabolic burden. However, currently there is no model that can computationally predict the plasmid copy number from the sequence of its origin of replication (ORI). We present a novel software solution tailored to s
