Introduction	Platinum and palladium are critical metals with high value at the nano-scale due to their catalytic properties. Desulfovibrio alaskensis can capture, reduce, and synthesise these metals into nanoparticles. This study investigates the proteins involved in the reductive pathways and stress-response system of this bacterium. A set of 13 core proteins was identified, with additional proteins specific to either metal. Overexpression of a platinum-specific gene led to larger nanoparticles. These insights enhance our understanding of metal resistance mechanisms, providing avenues for bioremediation and environmental metal capture.
