Hemoglobin in Frankia, a nitrogen-fixing actinomycete.
Frankia strain CcI3 grown in culture produced a hemoglobin which had optical absorption bands typical of a hemoglobin and a molecular mass of 14.1 kDa. Its equilibrium oxygen binding constant was 274 nM, the oxygen dissociation rate constant was 56 s(-1), and the oxygen association rate constant was 206 microM(-1) s(-1).
متن کاملIsolation of Mutants of the Nitrogen-Fixing Actinomycete Frankia
Frankia is a nitrogen (N)-fixing multicellular actinomycete which establishes root-nodule symbiosis with actinorhizal plants. Several aspects of Frankia N fixation and symbiosis are distinct, but genes involved in the specific features are largely unknown because of the lack of an efficient mutant screening method. In this study, we isolated mutants of Frankia sp. strain CcI3 using hyphae fragm...
متن کاملPermanent Draft Genome Sequence of Frankia sp. Strain AvcI1, a Nitrogen-Fixing Actinobacterium Isolated from the Root Nodules of Alnus viridis subsp. crispa Grown in Canada.
Frankia strain AvcI1, isolated from root nodules of Alnus viridis subsp. crispa, is a member of Frankia lineage Ia, which is able to reinfect plants of the Betulaceae and Myricaceae families. Here, we report a 7.7-Mbp draft genome sequence with a G+C content of 72.41% and 6,470 candidate protein-encoding genes.
متن کاملFormation and regeneration of protoplasts of the actinorhizal nitrogen-fixing actinomycete frankia.
Procedures for forming and regenerating protoplasts of four Frankia strains are described. Cells obtained from growth medium containing 0.1% glycine were digested with lysozyme (250 mug/ml) in a medium containing 0.5 M sucrose, 5.0 mM CaCl(2), and 5.0 mM MgCl(2). Protoplasts were formed during 15 to 120 min of digestion at 25 degrees C. Optimum conditions for protoplast regeneration involved pl...
متن کاملGenome Sequence of the Atypical Symbiotic Frankia R43 Strain, a Nitrogen-Fixing and Hydrogen-Producing Actinobacterium
Frankia strain R43 is a nitrogen-fixing and hydrogen-producing symbiotic actinobacterium that was isolated from nodules of Casuarina cunninghamiana but infects only Elaeagnaceae. This communication reports the genome of the strain R43 and provides insights into the microbe genomics and physiological potentials.
