Structure of the lipopeptide antibiotic tsushimycin

open access: yesActa Crystallographica Section D Biological Crystallography, 2005
The amphomycin derivative tsushimycin has been crystallized and its structure determined at 1.0 A resolution. The asymmetric unit contains 12 molecules and with 1300 independent atoms this structure is one of the largest solved using ab initio direct methods.

Establishment of a Human Cell‐Based In Vitro Test System for Investigating and Evaluating Cytotoxic and Immunomodulatory Effects of Indoor Mold

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Mold growth in damp indoor environments is a widespread problem associated with respiratory health effects, though causal mechanisms remain incompletely understood. We established a human cell‐based in vitro test system using bronchial epithelial cells (NuLi‐1) and macrophages (THP‐1) to assess inhalation toxicity and immunomodulatory effects ...

Peptide‐directed nanovehicles enabling tumor‐selective ROS amplification and antitumor immunity

open access: yesVIEW, EarlyView.
Cancer cells are vulnerable to oxidative stress, yet exploit immune tolerance to escape destruction. In contrast, their metabolic profile is markedly altered to support rapid proliferation, accompanied by elevated production of reactive oxygen species (ROS).

Insight into Antifungal Metabolites from Bacillus stercoris 92p Against Banana Cordana Leaf Spot Caused by Neocordana musae

open access: yesBiomolecules
Banana crop ranks among the most crucial fruit and food crops in tropical and subtropical areas. Despite advancements in production technology, diseases such as cordana leaf spot, caused by Neocordana musae, remain a significant challenge, reducing ...

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

open access: yesThe FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Immunostimulation by synthetic lipopeptide based vaccine candidates: structure-activity relationships.

open access: yesFrontiers in Immunology, 2013
Peptide based vaccines offer several advantages over conventional whole organism or protein approaches by offering improved purity and specificity in inducing immune response. However, peptides alone are generally non-immunogenic.

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Recent Advances in Toll Like Receptor-Targeting Glycoconjugate Vaccines

open access: yesMolecules, 2018
Many malignant cell surface carbohydrates resulting from abnormal glycosylation patterns of certain diseases can serve as antigens for the development of vaccines against these diseases.

Tripartite Interaction Between Penicillium pinophilum‐Host Plants and CMV‐Y: A Model for Endophyte‐Mediated Viral Biocontrol

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant‐fungus‐virus tripartite interactions represent complex ecological systems in which mutualistic endophytes can influence host physiology, yet the molecular basis of endophyte‐mediated defence remains poorly understood. Here, we demonstrate that the endophytic fungus Penicillium pinophilum EU0013 suppresses the yellow strain of cucumber ...

Genetic and functional characterization of the gene cluster directing the biosynthesis of putisolvin I and II in Pseudomonas putida strain PCL1445 [PDF]

open access: yes, 2008
Pseudomonas putida PCL1445 secretes two cyclic lipopeptides, putisolvin I and putisolvin II, which possess a surface-tension-reducing ability, and are able to inhibit biofilm formation and to break down biofilms of Pseudomonas species including ...
