Digital Microfluidics-Driven Cell-Free Protein Synthesis Platform Reveals Expression and Stability Determinants for Phytoglobins and Cysteine-to-Alanine Substituted Variants
Heme proteins are central to metabolism and stress responses but remain challenging to express recombinantly due to cytotoxicity and folding constraints. Phytoglobins (Pgbs) exemplify these difficulties, as expression protocols often fail to translate across protein species. Here, we used a cell-free protein synthesis (CFPS) platform powered by digital microfluidics to screen expression determinan
