12137512-0	2002	Iron-sulfur cluster biosynthesis: characterization of iron nucleation sites for assembly of the [2Fe-2S]2+ cluster core in IscU proteins.	Iron	54-58	iron-sulfur cluster assembly enzyme	Homo sapiens	123-127	
12137512-2	2002	The intermediate [2Fe-2S] IscU-bound cluster is formed by delivery of iron and sulfur to the apo-IscU, with the latter delivered through an IscS-mediated reaction.	Iron	70-74	iron-sulfur cluster assembly enzyme	Homo sapiens	26-30	
12137512-2	2002	The intermediate [2Fe-2S] IscU-bound cluster is formed by delivery of iron and sulfur to the apo-IscU, with the latter delivered through an IscS-mediated reaction.	Iron	70-74	iron-sulfur cluster assembly enzyme	Homo sapiens	97-101	
12137512-4	2002	In this report we characterize iron-binding sites on IscU that appear to nucleate [2Fe-2S] cluster assembly.	Iron	31-35	iron-sulfur cluster assembly enzyme	Homo sapiens	53-57	
12137512-5	2002	This iron-bound form of IscU is shown to be viable for subsequent IscS-mediated assembly of holo-IscU.	Iron	5-9	iron-sulfur cluster assembly enzyme	Homo sapiens	24-28	
12137512-5	2002	This iron-bound form of IscU is shown to be viable for subsequent IscS-mediated assembly of holo-IscU.	Iron	5-9	iron-sulfur cluster assembly enzyme	Homo sapiens	97-101	
12137512-7	2002	The latter observation reflects the low binding affinity of persulfido IscU for iron ion.	Iron	80-84	iron-sulfur cluster assembly enzyme	Homo sapiens	71-75
