The inducible isoform of nitric oxide synthase (iNOS) and three zinc tetrathiolate mutants (C104A, C109A, and C104A/C109A) were expressed in Escherichia coli and purified. The mutants were found by ICP-AES and the zinc-specific PAR colorimetric assay to be zinc free

In this study, X-ray photoelectron spectroscopy (XPS) was used to study chitosan-graphene oxide (chitosan-GO) incorporated with 4-(2-pyridylazo)resorcinol (PAR) and cadmium sulfide quantum dot (CdS QD) composite thin films for the potential optical sensing of cobalt ions (Co2+). From the XPS

In this study, three synthetic zinc-chelating peptides (ZCPs) derived from sea cucumber hydrolysates with limited or none of the common metal-chelating amino-acid residues were analyzed by flame atomic absorption spectroscopy, circular dichroism spectroscopy, size exclusion chromatography, zeta-potential, Fourier transform infrared

The biosynthesis of the dinuclear metal cluster at the active sites of the [NiFe]-hydrogenase enzymes is a multi-step process executed by a suite of accessory proteins. Nickel insertion during maturation of Escherichia coli [NiFe]-hydrogenase 3 is achieved by the metallochaperones

[NiFe]-hydrogenase, which catalyzes the reversible conversion between hydrogen gas and protons, is a vital component of the metabolism of many pathogens. Maturation of [NiFe]-hydrogenase requires selective nickel insertion that is completed, in part, by the metallochaperones SlyD and HypB. Escherichia
