IscA was proposed to be involved in the iron-sulfur cluster
assembly encoded by the iscSUA operon, but the role of
IscA in the iron-sulfur cluster assembly still remains
controversial. In our previous study, the IscA from A.
ferrooxidans was successfully expressed in Escherichia
coli, and purified to be a [Fe4S4]-cluster-containing protein.
Cys35, Cys99, and Cys101 were important residues in
ligating with the [Fe4S4] cluster. In this study, Asp97 was
found to be another ligand for the iron-sulfur cluster
binding according to site-directed mutagenesis results.
Molecular modeling for the IscA also showed that Asp97
was a strong ligand with the [Fe4S4] cluster, which was in
good agreement with the experimental results. Thus, the
[Fe4S4] cluster in IscA from A. ferrooxidans was ligated by
three cysteine residues and one aspartic acid.
