Systematic Evaluation of Signal Peptide-Driven Protein Secretion in the Fast-Growing Cyanobacterium Synechococcus sp. PCC 11901
This study establishes *Synechococcus* sp. PCC 11901 as a secretion-competent chassis for photosynthetic biomanufacturing by systematically evaluating signal peptides, revealing that while the Tat pathway leader FutA outperforms Sec candidates for eYFP, optimal signal peptide selection is cargo-dependent, as evidenced by the superior performance of the thermitase Sec signal for lichenase secretion.
