The bacterial CyaY proteins are iron-sulphur cluster (FeS) metabolism proteins which are homologous to eukaryotic frataxin. Partial phylogenetic profiling suggests that CyaY most likely functions as part of the ISC system for FeS cluster biosynthesis, and is supported by experimental data in some species.[1][2][3]
