Characterization and site-directed mutagenesis of NifU from Azotobacter vinelandii
In order to elucidate the function of the nifU gene product in nitrogenase maturation in Azotobacter vinelandii. the gene product has been hyperexpressed in Escherichia coli and characterized by various biophysical techniques. Following the initial characterization, site-directed mutagenesis of …

Biosynthesis of Iron-Sulfur Clusters
… system, it has been proposed that NifS and NifU are involved in the mobilization of sulfur and iron necessary for nitrogenase-specific [Fe-S] cluster assembly. The NifS protein has been shown to have cysteine desulfurase activity and can be used to supply sulfur for the <I>in</I> …

The Biosynthesis and Function of Nitrogenase Metalloclusters
… is a second point of interest. Inactivation of NifU or NifS has been shown to affect the activity of both nitrogenase components. NifS is a cysteine desulfurase that provides the sulfur for cluster formation and NifU serves as a molecular scaffold during [Fe-S] cluster assembly. Genetic and …

Genes from Arabidopsis involved in iron-sulfur cluster biogenesis
… proteins, which act as the sulfur donor, and the NifU/IscU/SufU proteins, which serve as a scaffold that binds Fe and upon which the cluster is assembled. Additional proteins are involved in the maturation and transport of the clusters. In eukaryotes there is redundancy in the proteins involved in …

Characterization of the nifUHD cluster and a new myoglobin-like gene from Nostoc commune UTEX 584
… 1988), determined the exact locations of the <i>nifU, nifH</i>, and <i>nifD</i> genes and identified two potential stem loop structures, a direct repeat, and an ORF that codes for a protein with a predicted amino acid sequence similar to that of myoglobin from <i>Paramecium caudatum</i>. The …

Assembly of Iron-Sulfur Clusters In Vivo
… a protein similar to the C-terminal domain of NifU, demonstrated that NfuA and similar proteins might serve as [Fe-S] cluster carriers to accomplish the efficient delivery of nascent cofactors to the various recipient proteins.
