Application

Application Comment Organism
environmental protection enzyme might be useful in development of a mechanism to remove contaminating uranium from groundwaters Desulfovibrio desulfuricans
environmental protection enzyme might be useful in development of a mechanism to remove contaminating uranium from groundwaters Desulfovibrio vulgaris

Protein Variants

Protein Variants Comment Organism
additional information a cytochrome c3 mutant strain I2 is impaired in reduction of uranium(VI) utilizing electrons from donors lactate, pyruvate or hydrogen transferred via cytochrome c3, the strongest effect is senn with hydrogen as electron donor Desulfovibrio desulfuricans
