Molecular basis for the impaired function of the natural F112L sorcin mutant: X-ray crystal structure, calcium affinity, and interaction with annexin VII and the ryanodine receptorThe crystal structure of the sorcin calcium binding domain provides a model of Ca2+-dependent processes in the full-length proteinThe Dps protein of Agrobacterium tumefaciens does not bind to DNA but protects it toward oxidative cleavage: x-ray crystal structure, iron binding, and hydroxyl-radical scavenging propertiesThe mutations Lys 114 --> Gln and Asp 126 --> Asn disrupt an intersubunit salt bridge and convert Listeria innocua Dps into its natural mutant Listeria monocytogenes Dps. Effects on protein stability at Low pHThermosynechococcus elongatus DpsA binds Zn(II) at a unique three histidine-containing ferroxidase center and utilizes O2 as iron oxidant with very high efficiency, unlike the typical Dps proteinsKineococcus radiotolerans Dps forms a heteronuclear Mn-Fe ferroxidase center that may explain the Mn-dependent protection against oxidative stressThe Salmonella enterica ZinT structure, zinc affinity and interaction with the high-affinity uptake protein ZnuA provide insight into the management of periplasmic zincSalmonella enterica serovar Typhimurium growth is inhibited by the concomitant binding of Zn(II) and a pyrrolyl-hydroxamate to ZnuA, the soluble component of the ZnuABC transporterThe yeast penta-EF protein Pef1p is involved in cation-dependent budding and cell polarization.Unusually strong H-bonding to the heme ligand and fast geminate recombination dynamics of the carbon monoxide complex of Bacillus subtilis truncated hemoglobin.Role of Dps (DNA-binding proteins from starved cells) aggregation on DNA.The multifaceted capacity of Dps proteins to combat bacterial stress conditions: Detoxification of iron and hydrogen peroxide and DNA binding.Iron and hydrogen peroxide detoxification properties of DNA-binding protein from starved cells.

A study with site-specific mutants.The truncated oxygen-avid hemoglobin from Bacillus subtilis: X-ray structure and ligand binding properties.Complex modulation of L-type Ca(2+) current inactivation by sorcin in isolated rabbit cardiomyocytes.The unusual intersubunit ferroxidase center of Listeria innocua Dps is required for hydrogen peroxide detoxification but not for iron uptake. A study with site-specific mutants.Evaluating cooperativity in dimeric hemoglobins.The ferritin-like protein Frm is a target for the humoral immune response to Listeria monocytogenes and is required for efficient bacterial survival.Study of manganese binding to the ferroxidase centre of human H-type ferritin.Periplasmic Cu,Zn superoxide dismutase and cytoplasmic Dps concur in protecting Salmonella enterica serovar Typhimurium from extracellular reactive oxygen species.Sorcin modulates cardiac L-type Ca2+ current by functional interaction with the alpha1C subunit in rabbits.
