Herbaspirillum aquaticum Dobritsa et al. 2010
2017Description of Herbaspirillum aquaticum LR-14 Cells are Gram negative and rod shaped. Grows on TSA at 30°C. Colonies are white colored, and undulate, smooth. Based on API20NE, cytochrome oxidase, β-glucosidase, protease and β-galactosidase activities are positive, but nitrate reduction, indole production, glucose fermentation, arginine dihydrolase and ...

The PII Protein of Herbaspirillum Seropedicae
1999The PII protein of Herbaspirillum seropedicae has been purified, crystallized and analysed for physical and biochemical properties. It is trimeric in solution, with a monomeric molecular weight of 12 kDa, comprising 112 amino acid residues, with a C-terminal loop absent from the E. coli PII.

Naringenin degradation by the endophytic diazotroph Herbaspirillum seropedicae SmR1
Microbiology, 2013Several bacteria are able to degrade flavonoids either to use them as carbon sources or as a detoxification mechanism. Degradation pathways have been proposed for several bacteria, but the genes responsible are not known. We identified in the genome of the endophyte Herbaspirillum seropedicae SmR1 an operon potentially associated with the degradation ...

Uridylylation of the PII protein fromHerbaspirillum seropedicae
Canadian Journal of Microbiology, 2001The PII protein is apparently involved in the control of NifA activity in Herbaspirillum seropedicae. To evaluate the probable role of PII in signal transduction, uridylylation assays were conducted with purified H. seropedicae PII and Escherichia coli GlnD, or a cell-free extract of H. seropedicae as sources of uridylylating activity.

Regulation of Nitrogen Fixation in Herbaspirillum seropedicae
1998Herbaspirillum seropedicae is an aerobic, plant-associated, nitrogen-fixing bacterium of the β-proteobacteria group. Nitrogen fixation in this organism is repressed by ammonium ions or oxygen, and nitrogenase switch-off by ammonium ions is partial and does not involve ADP-ribosylation (Klasssen et al., unpublished). The nif genes of H.

Role of conserved cysteine residues in Herbaspirillum seropedicae NifA activity
Research in Microbiology, 2009Herbaspirillum seropedicae is an endophytic diazotrophic bacterium that associates with economically important crops. NifA protein, the transcriptional activator of nif genes in H. seropedicae, binds to nif promoters and, together with RNA polymerase-sigma(54) holoenzyme, catalyzes the formation of open complexes to allow transcription initiation.

In vitro characterization of the NAD+ synthetase NadE1 from Herbaspirillum seropedicae
Archives of Microbiology, 2016Nicotinamide adenine dinucleotide synthetase enzyme (NadE) catalyzes the amination of nicotinic acid adenine dinucleotide (NaAD) to form NAD(+). This reaction represents the last step in the majority of the NAD(+) biosynthetic routes described to date. NadE enzymes typically use either glutamine or ammonium as amine nitrogen donor, and the reaction is ...
