DNA binding activity of NtrC from Rhizobium grown on different nitrogen sources

, 1994
The DNA-binding activity of the NtrC protein can be demonstrated in gel retardation assays with concentrated protein extracts of Rhizobium etli. Using extracts from either the wild type or a ntrC mutant strain and an antiserum raised against the NtrC ...

Alveolar Bone Regeneration: Smart Biomaterials and Physical Stimulation

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 4, April 2026.
ABSTRACT Large‐area bone loss from disease, trauma, or congenital defects requires surgical procedures and bone grafting. Alveolar bone loss from severe periodontal disease and non‐unions often demands immediate grafting. Treating large alveolar bone defects using grafts and substitutes is challenging due to the complex oral environment, infection ...

Quiescin Sulfhydryl Oxidase‐Like 1 Positively Regulates Seed Dormancy in Rice

Plant Biotechnology Journal, Volume 24, Issue 2, Page 489-503, February 2026.
ABSTRACT Seed dormancy is an adaptive strategy that enables plants to survive adverse environmental conditions. In agricultural contexts, an optimal level of dormancy is essential: Insufficient dormancy can result in preharvest sprouting, while excessive dormancy may lead to uneven germination and poor stand establishment in subsequent crops.

Experimental Confirmation of an NtrC Transition Pathway Predicted by Targeted MD [PDF]

Biophysical Journal, 2009
The infinitely short lifetime of transition states makes characterization extremely difficult. We have used a combination of molecular dynamics and experimental approaches to determine two important rate-limiting interactions involved in the allosteric transition of a signaling protein.

Comparison of Predatory Phenotypes and Genotypes Between Bdellovibrio sp. BIS2 and Bacteriovorax sp. HI3 Isolated From the Same Freshwater Environment

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Bdellovibrio and like organisms (BALOs) have gained attraction owing to their ecological and practical significance. This study comparatively investigated two BALO strains from the same freshwater pond, Bdellovibrio sp. BIS2 and Bacteriovorax sp. HI3, and revealed significant variation in their predatory behaviours and associated genetic profiles ...

Sigma factor N, liaison to an ntrC and rpoS dependent regulatory pathway controlling acid resistance and the LEE in enterohemorrhagic Escherichia coli. [PDF]

PLoS ONE, 2012
Enterohemorrhagic Escherichia coli (EHEC) is dependent on acid resistance for gastric passage and low oral infectious dose, and the locus of enterocyte effacement (LEE) for intestinal colonization.
