A Novel Ferric Reductase Purified from Magnetospirillum gryphiswaldense MSR-1

Current Microbiology, 2007
A ferric reductase was purified into an electrophoretically homologous state from Magnetospirillum gryphiswaldense MSR-1 strain. The enzyme was found within the cytoplasm and associated with the cytoplasmic membrane. The molecular weight of the purified enzyme was calculated as 16.1 kDa using sodium dodecyl sulfate-polyacrylamide gel electrophoresis ...

MamZ protein plays an essential role in magnetosome maturation process of Magnetospirillum gryphiswaldense MSR-1

Journal of Oceanology and Limnology, 2021
Based on analysis of gene structure of mamXY operon in Magnetospirillum gryphiswaldense strain MSR-1, we constructed a mamZ deletion mutant strain (ΔmamZ) and four complemented strains with different mamZ fragment lengths. Various cell phenotypic and physiological parameters were evaluated and compared among the wild-type (WT), mutant, and complemented

Magnetosomes eliminate intracellular reactive oxygen species in Magnetospirillum gryphiswaldense MSR‐1

Environmental Microbiology, 2012
Summary Magnetotactic bacteria synthesize magnetic particles called magnetosomes that cause them to orient to their external magnetic fields. However, the physiological significance and other possible functions of these magnetosomes have not been explored in detail.

Biosynthesis of gold nanoparticles by biosorption using Magnetospirillum gryphiswaldense MSR-1

Chemical Engineering Journal, 2011
Abstract The biosynthesis of nanoparticles is considered to be a novel, effective and eco-friendly procedure. In this paper, Magnetospirillum gryphiswaldense MSR-1 was successfully used to reduce gold ions to a zero-valent metal in a water environment, and more importantly, to accumulate them into spherical nanoparticles on the cell surface through

Disruption of a fur-like gene inhibits magnetosome formation in Magnetospirillum gryphiswaldense MSR-1

Biochemistry (Moscow), 2007
In this study, a genomic library of Magnetospirillum gryphiswaldense MSR-1 strain was constructed and a fur-like gene (encoding Fur protein, ferric uptake regulator) was isolated and sequenced. This gene consisted of 420 bp and encoded 139 amino acid residues.

mamO and mamE genes are essential for magnetosome crystal biomineralization in Magnetospirillum gryphiswaldense MSR-1

Research in Microbiology, 2010
Four non-magnetic mutants of Magnetospirillum gryphiswaldense strain MSR-1 were isolated by transposon mutagenesis and found to contain interruption of either the mamO or mamE gene within the mamAB operon. Studies indicated that mamO and mamE genes are essential for magnetosome crystal biomineralization in MSR-1.

A comprehensive assessment of the biocompatibility of Magnetospirillum gryphiswaldense MSR-1 bacterial magnetosomes in vitro and in vivo

Toxicology, 2021
Bacterial magnetosomes (BMs) are iron oxide nanoparticles synthesized naturally by magnetotactic bacteria, made up of nano-sized inorganic crystals enclosed by a lipid bilayer membrane. Due to several superior characteristics, such as the narrow size distribution, uniform morphology, high purity and crystallinity, single magnetic domain as well as easy
