EXAFS Reveals Two Mo Environments in the Nitrogenase Iron-Molybdenum Cofactor Biosynthetic Protein NifQ
George S.J.; Hernandez J.A.; Jimenez-Vicente E.; Echavarri-Erasun C.; Rubio L.M. Chem. Comm. 2016 52, 11811-11814
We use Mo and Fe EXAFS spectroscopy to show that the biosynthesis protein NifQ contains multiple kinds of molybdenum site.  This implies that NifQ may be a biosynthetic enzyme which converts molybdate into different chemical form which is then inserted into the Mo-Fe-S cofactor of nitrogenase, a key environmental enzyme.
This work is part of a collaboration with Luis Rubio of Centro de Biotechnología y Genómica de Plantas, UPM-INIA, Madrid, Spain and Jose Hernandez of Midwestern University, Glendale Arizona.

Interaction of Gd-DTPA with phosphate and phosphite: Toward the reaction intermediate in Nephrogenic Systemic Fibrosis
Gao, S.; George S.J.; Zhou Z-H. Dalton Trans. 2016, 45, 5388–5394
We show that phosphate can bind to gadolinium in the chelator DTPA, weakening the binding of the metal to it's chelator, a process that may well be the first step in the formation of gadolinium phosphate tissue deposits in the disease Nephrogenic Systemic Fibrosis.
This work is part of a collaboration with Zhao-Hui Zhou of the College of Chemistry and Chemical Engineering, Xiamen University, Xiamen, China.
