Proteins in which non-
haem iron is coordinated with cysteine sulfur
and usually also with inorganic sulfur. Divided into three major
categories: rubredoxins; '
simple iron-sulfur proteins', containing only
iron-sulfur clusters; and '
complex iron-sulfur proteins', containing
additional active redox centres such as
flavin, molybdenum or
haem.
In most iron-sulfur
proteins, the clusters function as electron-transfer
groups, but in others they have other functions, such as
catalysis of
hydratase/dehydratase reactions, maintenance of protein structure, or
regulation of activity.
