Facile Method for Site-specific Gene Integration in Lysobacter enzymogenes for Yield Improvement of the Anti-MRSA Antibiotics WAP-8294A and the Antifungal Antibiotic HSAF [PDF]

ACS Synthetic Biology, 2013
Lysobacter is a genus of Gram-negative gliding bacteria that are emerged as novel biocontrol agents and new sources of bioactive natural products. The bacteria are naturally resistant to many antibiotics commonly used in transformant selection, which has hampered the genetic manipulations.

The soil bacterium Lysobacter capsici attaches to the nematode surface, and triggers induced systemic resistance in barley, impairing the invasion of root‐lesion nematodes

Oikos, Volume 2025, Issue 4, April 2025.
Root‐lesion nematodes pose a global threat to crop yield and stability, with their broad host range presenting a formidable challenge for effective management. In this study, we investigated the role of the nematode‐attached bacterium Lysobacter capsici in mitigating the invasion of Pratylenchus penetrans into spring barley roots.

The Common Follicle-Stimulating Hormone Receptor (FSHR) Promoter Polymorphism FSHR −29G > A Affects Androgen Production in Normal Human Small Antral Follicles

Frontiers in Endocrinology, 2017
Follicle-stimulating hormone receptors (FSHRs) are almost exclusively expressed on granulosa cells, and FSH action is probably most clearly reflected in intrafollicular hormone milieu of antral follicles. Little is known about the possible effects of the

Erweiterung der Vielfalt der Kernstruktur von Polycyclischen Tetramsäure‐Haltigen Makrolactamen (PoTeMs) durch Chemo‐Enzymatische Synthese und Bio‐Engineering

Angewandte Chemie, Volume 137, Issue 13, March 24, 2025.
Polycyclische Tetramsäure‐haltige Makrolactame (PoTeMs) leiten sich vom Ornithin‐basierten Lysobacteren A ab. Um das Kohlenstoffgerüst der PoTeM‐Kernstruktur um eine CH2‐Einheit zu erweitern, wurden Lysobacteren A und ein verlängertes Analogon synthetisiert, und die Cyclisierung durch die Ikarugamycin‐Cyclasen IkaBC wurde in vitro erreicht ...

LeTetR Positively Regulates 3-Hydroxylation of the Antifungal HSAF and Its Analogs in \u3ci\u3eLysobacter enzymogenes\u3c/i\u3e OH11 [PDF]

, 2020
The biocontrol agent Lysobacter enzymogenes OH11 produces several structurally distinct antibiotic compounds, including the antifungal HSAF (Heat Stable Antifungal Factor) and alteramides, along with their 3-dehydroxyl precursors (3-deOH).

Hallmarks of Human Small Antral Follicle Development: Implications for Regulation of Ovarian Steroidogenesis and Selection of the Dominant Follicle

Frontiers in Endocrinology, 2018
Regulation of human ovarian steroidogenesis differs from other species and precise knowledge on how human small antral follicles (hSAF) develop and acquire competence for continued growth and steroid output is still incomplete.

Modular Tunable α‐Helical Peptide Hydrogels for Neuronal Cells

Advanced Functional Materials, Volume 35, Issue 1, January 2, 2025.
Rationally designed peptides are used to alter the elastic properties of α‐helical hydrogels, to introduce adhesion peptides and growth factors, and to spatially pattern proteins. The modularity of the hydrogelating self‐assembling fiber (hSAF) system provides a flexible platform for manipulating primary neural cell behavior, with potential future ...

Lsp family proteins regulate antibiotic biosynthesis in Lysobacter enzymogenes OH11

AMB Express, 2017
Ax21 family proteins have been shown to play regulatory roles in plant- and animal-pathogenic species in the bacterial family Xanthomonadaceae, but the protein have not been investigated previously in the non-pathogenic members of this bacterial family ...

Doing dams better? A case study of a proposed pumped hydro scheme at Lake Onslow, Central Otago

New Zealand Geographer, Volume 80, Issue 3, Page 220-232, December 2024.
Abstract Water resource managers and Geographers share common interests in meeting Sustainable Development Goal Seven (universal access to affordable energy) and addressing climate change. Hydropower plays a key role but dams have environmental, social and cultural consequences.

Robust gradient‐based neural networks for solving online the discrete periodic Lyapunov matrix equations

IET Control Theory &Applications, Volume 18, Issue 1, Page 71-82, January 2024.
Here, a gradient‐based neural network (GNN) model is constructed for solving the discrete periodic Lyapunov matrix equation associated with discrete‐time linear periodic systems. A novel type of non‐linear activation function is applied to the GNN model, which makes the GNN model to achieve better convergence and robustness.
