What is fe2s?

Fe2S, also known as diiron sulfide or iron-sulfur cluster, is a compound consisting of two iron atoms and two sulfur atoms that are bonded together. In biological systems, Fe2S is an important cofactor found in many proteins and enzymes, where it plays a crucial role in electron transfer reactions. Fe2S-containing proteins are involved in various physiological processes, including respiration, photosynthesis, nitrogen fixation, and DNA repair. Fe2S clusters have also been studied for their potential applications in catalysis and electronic devices. The properties and functions of Fe2S clusters are highly dependent on their coordination environment, which can be tuned by various chemical modifications.
