  "term": "Iron-sulfur proteins",
  "field": "Chemistry",
  "definition": "A class of proteins whose redox centres are non-haem iron atoms held by cysteine sulfur, usually together with inorganic sulfide, as in Fe2S2 and Fe4S4 clusters and the single-iron rubredoxin site. Most act as electron carriers in respiration and photosynthesis, while some catalyse reactions or regulate activity. The complex members add a second kind of active group, for instance a flavin, a molybdenum site or a haem.",
