Comparative Genomics of 9 Novel Paenibacillus Larvae Bacteriophages [PDF]

open access: yes, 2016
American Foulbrood Disease, caused by the bacterium Paenibacillus larvae, is one of the most destructive diseases of the honeybee, Apis mellifera. Our group recently published the sequences of 9 new phages with the ability to infect and lyse P.

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Bacteriophage induction versus vaginal homeostasis: role of H2O2 in the selection of Lactobacillus defective prophages [PDF]

open access: yes, 2010
Vaginal disorders associated with systemic chemotherapy arise by direct inhibition of the resident microbiota (dominated by lactobacilli) or, possibly, by induction of prophages harbored in their genomes, leading to cell lysis.

Giant number fluctuations in microbial ecologies

open access: yes, 2012
Statistical fluctuations in population sizes of microbes may be quite large depending on the nature of their underlying stochastic dynamics. For example, the variance of the population size of a microbe undergoing a pure birth process with unlimited ...

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 ...

Network Models of Phage-Bacteria Coevolution [PDF]

open access: yes, 2006
Bacteria and their bacteriophages are the most abundant, widespread and diverse groups of biological entities on the planet. In an attempt to understand how the interactions between bacteria, virulent phages and temperate phages might affect the ...

Phage Therapy: Targeting the Gut Microbiota for the Treatment of Acute Pancreatitis

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Acute pancreatitis (AP) is a common clinical inflammatory condition whose severity is closely associated with both local pancreatic injury and systemic complications. Research indicates that gut microbiota dysbiosis and subsequent bacterial translocation can exacerbate disease progression via the gut–pancreas axis, representing a critical ...

The gp44 Ejection Protein of Staphylococcus aureus Bacteriophage 80α Binds to the Ends of the Genome and Protects It from Degradation

open access: yesViruses, 2020
Bacteriophage 80α is a representative of a class of temperate phages that infect Staphylococcus aureus and other Gram-positive bacteria. Many of these phages carry genes encoding toxins and other virulence factors.

Comprehensive and Comparative Transcriptional Profiling of the Cell Wall Stress Response in Bacillus subtilis

open access: yesMolecular Microbiology, EarlyView.
Transcriptional profiling of the primary cell envelope stress response (CESR) of Bacillus subtilis exposed to a range of cell wall‐targeting antimicrobials, combining RNAseq and high‐resolution tiling arrays. We revealed the complexity of the CESR, the contribution of extracytoplasmic function sigma factors (ECFs) and two‐component signal transduction ...
