UVSX recombinant protein is a key component derived from bacteriophage recombination systems, primarily studied for its role in facilitating homologous DNA recombination in vitro. Originally identified in bacteriophage T4. the UVSX gene encodes a protein that functions analogously to bacterial RecA, promoting strand exchange between homologous DNA molecules—a critical step in DNA repair and genetic recombination. This protein has garnered significant attention in molecular biology and genetic engineering due to its ability to enhance the efficiency of DNA assembly and editing workflows.
Structurally, UVSX forms helical filaments on single-stranded DNA (ssDNA), enabling it to search for homology in double-stranded DNA (dsDNA) and catalyze strand invasion. Unlike some eukaryotic recombinases, UVSX operates without requiring ATP hydrolysis, relying instead on ssDNA-binding proteins like UVSY for stabilization. This ATP-independent mechanism simplifies its application in synthetic biology tools, making it particularly useful for in vitro DNA manipulation techniques such as Gibson Assembly and CRISPR-based genome editing enhancements.
Recent advancements have leveraged UVSX in CRISPR-Cas systems to improve homology-directed repair (HDR) efficiency, addressing a major bottleneck in precise genome editing. Its thermostability and compatibility with diverse experimental conditions further broaden its utility in diagnostic assays, synthetic genome construction, and high-throughput DNA cloning. Researchers continue to explore engineered variants of UVSX to optimize activity, specificity, and compatibility with emerging gene-editing technologies, positioning it as a versatile tool for next-generation biomanufacturing and therapeutic development.
