NiFe hydrogenase

NiFe hydrogenase is an enzyme that helps certain microorganisms produce or utilize hydrogen gas (H₂). It contains a metal center made of nickel and iron, which facilitates the transfer of electrons during the process. Essentially, the enzyme enables biological systems to generate energy by splitting hydrogen molecules or regenerating hydrogen from protons, playing a crucial role in microbial metabolism and energy flow. Its ability to catalyze these reactions efficiently makes it of interest for renewable energy research, such as hydrogen fuel production.
