Ultrahigh-throughput discovery and engineering of enzymes for biotechnological applications

Research summary:

Microbial diversity is a vast reservoir of genetic information that can be valorized through industrial application, from biosynthetic gene clusters to novel protein catalysts. The synergy between new experimental discovery tools based on biology and those based on nanotechnologies are instrumental to find relevant genes faster and more efficiently, enabling especially academic labs to undertake screening campaigns until now costly and limited to large enterprises.

En nuestro laboratorio utilizamos selecciones biológicas o métodos de cribado de ultra-alta capacidad basados en microfluídica para encontrar genes y enzimas de interés en la diversidad natural o artificial. Las selecciones biológicas acoplan la mejora en una propiedad de interés a la supervivencia de un huésped bajo presión de selección. Utilizando este y otros métodos de ingeniería de proteínas hemos desarrollado variantes estables y solubles de enzimas para biocatálisis, como esterasas, deshalogenasas, además de proteínas fluorescentes para aplicaciones de localización in vivo a altas temperaturas.

However, the complexity of cellular metabolism limits the application of biological selections. Microfluidics enables the miniaturization of assays with throughput of kHz and a 1000x reduction in volume and costs. Therefore, droplet microfluidics achieves throughputs typical of biological selections with none of their complexity. Within the H2020 project MetaFluidics, in our laboratory, we have implemented a fluorescence-based microfluidic sorting platform and assays to find stable hydrolases in thermal environments as well as other relevant enzymes for biocatalysis. This has entailed developing news hosts and methods for functional expression, compatible with enzymatic assays at high temperatures.
