New Nonheme Iron Proteins Findings Has Been Reported by Investigators at University of Florence (H-1, C-13 and N-15 Assignment of the Human Mitochondrial Paramagnetic Iron-sulfur Protein Cisd3)

Article Description

CISD3 is a mitochondrial protein that contains two [2Fe–2S] clusters. This protein is overexpressed in some types of cancer, so it has emerged as a potential drug target. A detailed characterization of this protein is crucial to understand how CISD3 is involved in these physiopathologies. In this study, isotopically labeled human CISD3 was expressed in Escherichia coli. A set of double and triple resonance experiments performed with standard parameters/datasets provided the assignment of 40% of the HN resonances, 47% of Cα, and 46% of C′ resonances. Tailored paramagnetic HSQC, CON and CACO experiments extended up to 59% for HN, 70% for Cα and 69% for C′. The H, C and N NMR chemical shift assignment of human CISD3 is reported here.
