Analysis of Nitrogenase Fe Protein Activity in Transplastomic Tobacco
Frontiers in Agronomy, 2021 Integration of prokaryotic nitrogen fixation (nif) genes into the plastid genome for expression of functional nitrogenase components could render plants capable of assimilating atmospheric N2 making their crops less dependent of nitrogen fertilizers. The

Mössbauer spectroscopy of Fe/S proteins
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2015 Iron-sulfur (Fe/S) clusters are structurally and functionally diverse cofactors that are found in all domains of life. (57)Fe Mössbauer spectroscopy is a technique that provides information about the chemical nature of all chemically distinct Fe species contained in a sample, such as Fe oxidation and spin state, nuclearity of a cluster with more than ...

Nitrogenase Fe protein: A molybdate/homocitrate insertase [PDF]
Proceedings of the National Academy of Sciences, 2006 The Fe protein is indispensable for nitrogenase catalysis and biosynthesis. However, its function in iron-molybdenum cofactor (FeMoco) biosynthesis has not been clearly defined. Here we show that the Fe protein can act as a Mo/homocitrate insertase that mobilizes Mo/homocitrate for the maturation of FeMoco precursor on NifEN. Further, we establish that

Investigating the Interaction of Fe Nanoparticles with Lysozyme by Biophysical and Molecular Docking Studies. [PDF]
PLoS ONE, 2016 Herein, the interaction of hen egg white lysozyme (HEWL) with iron nanoparticle (Fe NP) was investigated by spectroscopic and docking studies. The zeta potential analysis revealed that addition of Fe NP (6.45±1.03 mV) to HEWL (8.57±0.54 mV) can cause to ...

Expression of the mammalian c-fes protein in hematopoietic cells and identification of a distinct fes-related protein. [PDF]
Molecular and Cellular Biology, 1985 The avian c-fps and mammalian c-fes proto-oncogenes are cognate cellular sequences. Antiserum raised against the P140gag-fps transforming protein of Fujinami avian sarcoma virus specifically recognized a 92,000-Mr protein in human and mouse hematopoietic cells which was closely related in structure to Snyder-Theilen feline sarcoma virus P87gag-fes ...

The NMR contribution to protein–protein networking in Fe–S protein maturation [PDF]
JBIC Journal of Biological Inorganic Chemistry, 2018 Iron-sulfur proteins were among the first class of metalloproteins that were actively studied using NMR spectroscopy tailored to paramagnetic systems. The hyperfine shifts, their temperature dependencies and the relaxation rates of nuclei of cluster-bound residues are an efficient fingerprint of the nature and the oxidation state of the Fe-S cluster ...

Mechanism of Iron–Sulfur Cluster Assembly: In the Intimacy of Iron and Sulfur Encounter
Inorganics, 2020 Iron–sulfur (Fe–S) clusters are protein cofactors of a multitude of enzymes performing essential biological functions. Specialized multi-protein machineries present in all types of organisms support their biosynthesis.

Frontiers in Physiology, 2017 Background: In production animal agriculture, the cost of feed represents 60–70% of the total cost of raising an animal to market weight. Thus, development of viable biomarkers for feed efficiency (FE, g gain/g feed) to assist in genetic selection of ...
