Draft Genome Sequences of Two Magnetotactic Bacteria, Magnetospirillum moscoviense BB-1 and Magnetospirillum marisnigri SP-1
We report here the draft genome sequences of two recently isolated magnetotactic species, Magnetospirillum moscoviense BB-1 and Magnetospirillum marisnigri SP-1. The genome of M. moscoviense BB-1 has 4,164,497 bp, 65.2% G+C content, and comprises 207 contigs. The genome of M. marisnigri SP-1 consists of 131 contigs and has a length of 4,619,819 bp and 64.7% G+C content.
متن کاملSurface Engineering of Iron Oxide Nanoparticles Isolated from Magnetospirillum Gryphiswaldense for Biochemical and Biomedical Applications
Superparamagnetic iron oxide nanoparticles with appropriate surface modification can be widely used in various applications including magnetic resonance imaging (MRI) diagnostic contrast agents, anticancer therapy using hyperthermia, magnetic drug targeting, protein and enzyme immobilization, cell labeling and separation or RNA and DNA purification. All these biochemical and biomedical applicat...
متن کاملTranscriptional organization and regulation of magnetosome operons in Magnetospirillum gryphiswaldense.
Genes involved in magnetite biomineralization are clustered within the genomic magnetosome island of Magnetospirillum gryphiswaldense. Their transcriptional organization and regulation were studied by several approaches. Cotranscription of genes within the mamAB, mamDC, and mms clusters was demonstrated by reverse transcription-PCR (RT-PCR) of intergenic regions, indicating the presence of long...
متن کاملEnzymatic Iron Oxidation and Reduction in Magnetite Synthesizing Magnetospirillum Magnetotacticum
We investigated the enzymatic reduction and oxidation of iron in M.magnetotacticum which synthesizes magnetite at room temperature. NADH-Fe(lI1) reductase with the molecular mass of 36kDa was purified from the bacterium. The enzyme was located in cytoplasm and utilized NADH and NADPH in the presence of FMN as reductant and showed maximum activity at pH 7.0. The Km for NADH and NADPH were about ...
متن کاملEffect of Magnetospirillum gryphiswaldense on serum iron levels in mice
BACKGROUND AND OBJECTIVES The Magnetotactic bacterium Magnetospirillumgryphiswaldense (MSR-1) mineralizes the magnetite (Fe(3) O(4)) crystals and organizes a highly ordered intracellular structure, called the magnetosome. Iron transport system supports the biogenesis of magnetite. Although iron is an essential trace element for many metabolic pathways of the body, increase or decrease in iron w...
