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

The paper engineers a cyanobacterial strain to control PEB metabolism, enabling reversible color shifts and structural changes in phycobilisomes for improved light harvesting.

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.
