This paper introduces a heterologous SPS biosynthesis system into Synechococcus elongatus PCC 7942, enabling the production of synechan, a novel sulfated polysaccharide.

This study identifies two novel replication proteins, CyRepX1 and CyRepX2, from a cyanobacterial plasmid and demonstrates their compatibility with existing replication systems, suggesting potential applications in genetic engineering.

This study identifies an autonomous replication region in cyanobacteria and develops an expression vector system using it, demonstrating broad host compatibility and inducible gene expression.
