A metagenomic survey of the fecal microbiome of the African savanna elephant (Loxodonta africana)

Animal Genetics, Volume 55, Issue 4, Page 621-643, August 2024.
Abstract The African savanna elephant (Loxodonta africana) is the largest terrestrial animal on Earth and is found primarily in Southern and Eastern Africa. It is a hindgut, colonic fermenter and subsists on a diet of raw plant materials found in its grazing area.

Cleavage of an engulfment peptidoglycan hydrolase by a sporulation signature protease in Clostridioides difficile

Molecular Microbiology, Volume 122, Issue 2, Page 213-229, August 2024.
Model for the cleavage of SpoIIP by SpoIVB2 during sporulation in Clostridioides difficile. Soon after engulfment completion, SpoIVB2 cleaves SpoIIP, part of the engulfasome complex, to generate the SpoIIPc form. The function of SpoIVB2 is required for synthesis of the cortex layer which takes place across the outer forespore membrane.

A Lytic Transglycosylase of Neisseria gonorrhoeae Is Involved in Peptidoglycan-Derived Cytotoxin Production

, 2002
Neisseria gonorrhoeae releases soluble fragments of peptidoglycan during growth. These molecules are implicated in the pathogenesis of various forms of gonococcal infection. A major peptidoglycan fragment released by gonococci is identical to

Characterization of the Nonconserved hpaB-hrpF Region in the hrp Pathogenicity Island from Xanthomonas campestris pv. vesicatoria

Molecular Plant-Microbe Interactions, 2007
The interaction of the gram-negative phytopathogenic bacterium Xanthomonas campestris pv. vesicatoria with its host plants pepper and tomato is mediated by a type III secretion (T3S) system that translocates bacterial effector proteins into the plant ...

Diversity and Distribution of a Novel Genus of Hyperthermophilic Aquificae Viruses Encoding a Proof-Reading Family-A DNA Polymerase

Frontiers in Microbiology, 2020
Despite the high abundance of Aquificae in many geothermal systems, these bacteria are difficult to culture and no viruses infecting members of this phylum have been isolated. Here, we describe the complete, circular dsDNA Uncultivated Virus Genome (UViG)

Determinants in the phage life cycle: The dynamic nature of ssDNA phage FLiP and host interactions under varying environmental conditions and growth phases

Environmental Microbiology, Volume 26, Issue 7, July 2024.
The interactions between the lipid‐containing ssDNA phage FLiP and its three Flavobacterium hosts are influenced by factors such as the host strain and culture conditions, including temperature and bacterial growth phase. Abstract The influence of environmental factors on the interactions between phages and bacteria, particularly single‐stranded DNA ...

Structure and Cell Wall Cleavage by Modular Lytic Transglycosylase MltC of Escherichia coli

, 2015
The lytic transglycosylases are essential bacterial enzymes that catalyze the nonhydrolytic cleavage of the glycan strands of the bacterial cell wall.

The DigH glycosyl hydrolase is conditionally required for daughter cell separation in Escherichia coli

Journal of Bacteriology
The peptidoglycan (PG) cell wall is a mesh-like layer that shapes bacteria and protects against osmotically induced lysis. PG is composed of glycan strands and peptide chains that link together to form a continuous layer that surrounds the cell.
