Re-engineered transcriptional regulation of hydrogenase • to achieve four-fold higher activity (from 0.5 to 2 nmol H2*mg protein *h). Examined the effect of transcriptional modifications on • hydrogenase maturation and found that proper regulation of accessory genes is essential for optimal hydrogenase maturation. Created mutants of the environmentally-derived • hydrogenase small subunit with f...
