Mechanism of Lysobacter enzymogenes resistance toward fungi induced by fungal-derived signal α-terpinene [PDF]

Applied and Environmental Microbiology
Bacterial-fungal interactions (BFI) are critical drivers of ecosystem functions, and their molecular mechanisms remain incompletely understood. Chemical signals are crucial mediators of microbial communication, but the signaling mechanisms of terpene ...

Synthesis of a 2,4,6,8,10-dodecapentanoic acid thioester as a substrate for biosynthesis of heat stable antifungal factor (HSAF) [PDF]

RSC Advances, 2015
The N-acetylcystamine (SNAC) thioester of dodecapentaenoic acid, an analog of a putative intermediate in the biosynthesis of Heat Stable Antifungal Factor (HSAF), is synthesized.

Clp is a “busy” transcription factor in the bacterial warrior, Lysobacter enzymogenes [PDF]

Computational and Structural Biotechnology Journal, 2021
Cyclic AMP receptor protein (CRP) is a well-characterized group of global transcription factors in bacteria. They are known to regulate numerous cellular processes by binding DNA and/or cAMP (a ligand called bacterial second messenger) to control target ...

Efficient production of heat-stable antifungal factor through integrating statistical optimization with a two-stage temperature control strategy in Lysobacter enzymogenes OH11

BMC Biotechnology, 2018
Background Heat-stable antifungal factor (HSAF) is a newly identified broad-spectrum antifungal antibiotic from the biocontrol agent Lysobacter enzymogenes and is regarded as a potential biological pesticide, due to its novel mode of action. However, the

The Dam Industry, the World Commission on Dams and the HSAF Process

Water Alternatives, 2010
Most actors of the global dam industry primarily operate within their national borders, and are either controlled by or do most of their business with the state.

Biosynthesis of the Polycyclic System in the Antifungal HSAF and Analogues from Lysobacter enzymogenes [PDF]

Angewandte Chemie, 2018
AbstractThe biocontrol agent Lysobacter enzymogenes produces polycyclic tetramate macrolactams (PoTeMs), including the antifungal HSAF. To elucidate the biosynthesis of the cyclic systems, we identified eleven HSAF precursors/analogues with zero, one, two, or three rings through heterologous expression of the HSAF gene cluster.

Expanding Polycyclic Tetramate Macrolactam (PoTeM) Core Structure Diversity by Chemo-Enzymatic Synthesis and Bioengineering. [PDF]

Angew Chem Int Ed Engl
Polycyclic tetramate macrolactams (PoTeMs) derive from ornithine‐based lysobacterene A. To expand the PoTeM core structure carbon skeleton by a CH2‐unit, a synthetic access to lysobacterene A and an extended analog was developed, and cyclization by cognate ikarugamycin cyclases IkaBC was achieved in vitro.

A TonB-dependent receptor regulates antifungal HSAF biosynthesis in Lysobacter [PDF]

Scientific Reports, 2016
AbstractLysobacter species are Gram-negative bacteria that are emerging as new sources of antibiotics, including HSAF (Heat Stable Antifungal Factor), which was identified from L. enzymogenes with a new mode of action. LesR, a LuxR solo, was recently shown to regulate the HSAF biosynthesis via an unidentified mechanism in L. enzymogenes OH11.

Diffusion Hammerstein Spline Adaptive Filtering Based on Orthogonal Gradient Adaptive Algorithm

IEEE Access, 2022
In this paper, we propose a class of nonlinear diffusion filtering based on Hammerstein function with the spline adaptive filter (HSAF) implemented by normalised version of orthogonal gradient adaptive (NOGA) algorithm over the distributed network ...
