An ASCA Study of the Heavy Element Distribution in Clusters of Galaxies

, 2000
We perform a spatially resolved X-ray spectroscopic study of a set of 11 relaxed clusters of galaxies observed by the ROSAT/PSPC and ASCA/SIS. Using a method which corrects for the energy dependent effects of the ASCA PSF based on ROSAT images, we ...

Structure of human Fe–S assembly subcomplex reveals unexpected cysteine desulfurase architecture and acyl-ACP–ISD11 interactions [PDF]

, 2017
In eukaryotes, sulfur is mobilized for incorporation into multiple biosynthetic pathways by a cysteine desulfurase complex that consists of a catalytic subunit (NFS1), LYR protein (ISD11), and acyl carrier protein (ACP). This NFS1-ISD11-ACP (SDA) complex

The diversity and applications of microbial iron metabolism and iron-containing proteins

Communications Biology
This collection reflects research that will advance the understanding of hemoproteins, iron-sulfur cluster proteins and other iron-containing proteins, proteins involved in homeostasis of iron/heme and their regulation, or ecological impacts of iron/heme

Physiologically relevant reconstitution of iron-sulfur cluster biosynthesis uncovers persulfide-processing functions of ferredoxin-2 and frataxin

Nature Communications, 2019
The mechanism of iron-sulfur (Fe-S) cluster biosynthesis is not fully understood. Here, the authors develop a physiologically relevant in vitro model of Fe-S cluster assembly, allowing them to elucidate the sequence of Fe-S cluster synthesis along with ...

The site of synthesis of the iron-sulfur subunits of the flavoprotein and iron-protein fractions of human NADH dehydrogenase [PDF]

, 1988
The site of synthesis of the iron-sulfur subunits of the flavoprotein and iron-protein fractions of the human respiratory chain NADH dehydrogenase has been investigated to test the possibility that any of them is synthesized in mitochondria.

A Method for Deriving Accurate Gas-Phase Abundances for the Multiphase Interstellar Galactic Halo

, 2005
We describe a new method for determining total gas-phase abundances for the Galactic ISM with minimal ionization uncertainties. For sight lines toward globular clusters containing both UV-bright stars and radio pulsars, one can measure column densities ...

Hsc66 substrate specificity is directed toward a discrete region of the iron-sulfur cluster template protein IscU [PDF]

, 2002
Hsc66 and Hsc20 comprise a specialized chaperone system important for the assembly of iron-sulfur clusters in Escherchia coli. Only a single substrate, the Fe/S template protein IscU, has been identified for the Hsc66/Hsc20 system, but the mechanism by ...

Opposite Regulatory Effects of Iron Ions on the In Vitro Catalytic Activities of NarE, the Toxin-like ADP-ribosyltransferase from Neisseria meningitidis [PDF]

, 2015
NarE, the mono ADP-ribosyltransferase identified in Neisseria meningitidis, catalyzes three enzymatic reactions. NarE transfers a single ADP-ribose unit to guanidine compounds, hydrolyses NAD in nicotinamide and free ADP-ribose, and ADP-ribosylates ...

Contribution of Type Ia and Type II Supernovae for Intra-Cluster Medium Enrichment

, 1998
The origin of the chemical composition of the intracluster medium (ICM) is discussed in this paper. In particular, the contribution from Type Ia supernovae (SNe Ia) to the ICM enrichment is shown to exist by adopting the fitting formulas which have been ...
