A transthyretin-related protein is functionally expressed in Herbaspirillum seropedicae

Biochemical and Biophysical Research Communications, 2009
Transthyretin-related proteins (TRPs) constitute a family of proteins structurally related to transthyretin (TTR) and are found in a large range of bacterial, fungal, plant, invertebrate, and vertebrate species. However, it was recently recognized that both prokaryotic and eukaryotic members of this family are not functionally related to transthyretins.

Toxicity of herbicides used in the sugarcane crop to diazotrophic bacterium Herbaspirillum seropedicae

Semina: Ciências Agrárias, 2014
The objective of this work was to identify herbicides used in the sugarcane crop that affects neither the growth, the development, of nor the process of biological nitrogen fixation (BNF) by the diazotrophic bacterium Herbaspirillum seropedicae. Eighteen

Isolation and Characterization of Herbaspirillum seropedicae Z78 Lipopolysaccharide

Izvestiya of Saratov University. Chemistry. Biology. Ecology, 2011
Lipopolysaccharide (LPS) preperations were isolated from the outer membrane of the bacterium Herbaspirillum seropedicae Z78 by using various methods. SDS electrophoresis revealed that the samples were heterogeneous in nature and that R-form molecules were predominant.

Control of Herbaspirillum seropedicae NifA Activity by Ammonium Ions and Oxygen [PDF]

Journal of Bacteriology, 1999
ABSTRACT The activity of a truncated form of Herbaspirillum seropedicae NifA in different genetic backgrounds showed that its regulatory domain is involved in nitrogen control but not in O 2 sensitivity or Fe dependence.

History on the biological nitrogen fixation research in graminaceous plants: special emphasis on the Brazilian experience

Anais da Academia Brasileira de Ciências, 2005
This review covers the history on Biological Nitrogen Fixation (BNF) in Graminaceous plants grown in Brazil, and describes research progress made over the last 40 years, most of whichwas coordinated by Johanna Döbereiner.

Expression and functional analysis of an N‐truncated NifA protein of Herbaspirillum seropedicae [PDF]

FEBS Letters, 1999
In Herbaspirillum seropedicae, an endophytic diazotroph, nif gene expression is under the control of the transcriptional activator NifA. We have over‐expressed and purified a protein containing the central and C‐terminal domains of the H. seropedicae NifA protein, N‐truncated NifA, fused to a His‐Tag sequence.

Extending Cofactor‐Tethered Nanomachines to Complex Multienzyme Redox Cascades in Continuous Flow

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
Engineered enzyme fusions bearing covalently tethered PEG–nicotinamide cofactors enable intramolecular cofactor retention and recycling within self‐sufficient biocatalytic nanomachines. These nanomachines support cofactor‐autonomous operation of complex redox multienzyme cascades under continuous‐flow conditions, as demonstrated in a 10‐step glucose‐to‐

Phage antibodies for the immunochemical characterization of Herbaspirillum seropedicae Z78 glycopolymers [PDF]

Annals of Microbiology, 2019
Microbial carbohydrate antigens are targets of the immune systems of hosts. In this context, it is of interest to obtain data that will permit judgment of the degree of heterogeneity, chemical makeup, and localization of the antigenic determinants of the Herbaspirillum surface glycopolymers. A sheep single-chain antibody-fragment phage library (Griffin.

DNA Methylation Shapes Seed‐Borne Microbiome and Proteome Responses During Early Maize‐Beneficial Bacteria Interactions

Plant, Cell &Environment, Volume 49, Issue 8, Page 5477-5496, August 2026.
ABSTRACT Microorganism and plant interactions are crucial for development and environmental adaptation. Plant growth promoting bacteria enhance agricultural productivity in a sustainable manner, while epigenetic modifications such as DNA methylation regulate gene expression and adaptive responses.
