Question

List three plant proteins/enzymes that contain the 3Fe-4S cluster. (Reference: Balk and Pilon [2011] Trends in Plant Science 16: 218-226. See the supplemental material of this reference) List any four plant proteins/enzymes that contain the 4Fe-4S cluster. (Reference: Balk and Pilon [2011] Trends in Plant Science 16: 218-226. See the supplemental material of this reference) There are three Fe-S cluster assembly pathways in plant cells: the sulfur mobilization (SUF) pathway in plastids (stroma), the iron-sulfur cluster (ISC) pathway in mitochondria (matrix), and the cytosolic iron-sulfur protein assembly (CIA) proteins in the cytosol. Use diagrams illustrating these three pathways. Make sure you include all the known proteins involved in these three pathways.
