ElaD, a Deubiquitinating Protease Expressed by E. Coli [PDF]

open access: yes, 2011
Background: Ubiquitin and ubiquitin-like proteins (Ubl) are designed to modify polypeptides in eukaryotes. Covalent binding of ubiquitin or Ubls to substrate proteins can be reversed by specific hydrolases.

BEAN and HABAS: Polyphyletic insertions in the DNA‐directed RNA polymerase

open access: yesProtein Science, Volume 33, Issue 11, November 2024.
Abstract The β and β′ subunits of the RNA polymerase (RNAP) are large proteins with complex multi‐domain architectures that include several insertional domains. Here, we analyze the domain organizations of RNAP‐β and RNAP‐β′ using sequence, experimentally determined structures and AlphaFold structure predictions.

Signature sequences in diverse proteins provide evidence for the late divergence of the Order Aquificales [PDF]

open access: yes, 2010
The Aquificales species are presently believed to be the earliest branching lineage within Bacteria. However, the branching order of this group in different phylogenetic trees is highly variable and not resolved.

An Ancient Molecular Arms Race: Chlamydia vs. Membrane Attack Complex/Perforin (MACPF) Domain Proteins

open access: yesFrontiers in Immunology, 2020
Dynamic interactions that govern the balance between host and pathogen determine the outcome of infection and are shaped by evolutionary pressures. Eukaryotic hosts have evolved elaborate and formidable defense mechanisms that provide the basis for ...

Cell wall precursors are required to organize the chlamydial division septum. [PDF]

open access: yes, 2014
Members of the Chlamydiales order are major bacterial pathogens that divide at mid-cell, without a sequence homologue of the FtsZ cytokinetic tubulin and without a classical peptidoglycan cell wall.

Gamma-Interferon-Induced Nitric-Oxide Production Reduces Chlamydia-Trachomatis Infectivity in McCoy Cells [PDF]

open access: yes, 1993
McCoy cells, murine-derived cells commonly used for propagation of chlamydiae, were found to be efficient producers of nitric oxide (NO) when primed with murine gamma interferon (IFN-gamma) and then exposed to the second signals provided by Escherichia ...

Supplementation of lactobacillus‐fermented rapeseed meal in broiler diet reduces Campylobacter jejuni cecal colonization and limits the l‐tryptophan and l‐histidine biosynthesis pathways

open access: yesJournal of the Science of Food and Agriculture, Volume 104, Issue 9, Page 5474-5485, July 2024.
Abstract BACKGROUND Campylobacter jejuni (C. jejuni), a widely distributed global foodborne pathogen, primarily linked with contaminated chicken meat, poses a significant health risk. Reducing the abundance of this pathogen in poultry meat is challenging but essential.

Chlamydia trachomatis’ struggle to keep its host alive

open access: yesMicrobial Cell, 2017
Bacteria of the phylum Chlamydiae infect a diverse range of eukaryotic host species, including vertebrate animals, invertebrates, and even protozoa. Characteristics shared by all Chlamydiae include their obligate intracellular lifestyle and a biphasic ...

Absence of Specific Chlamydia trachomatis Inclusion Membrane Proteins Triggers Premature Inclusion Membrane Lysis and Host Cell Death

open access: yesCell Reports, 2017
Chlamydia trachomatis is a human pathogen associated with significant morbidity worldwide. As obligate intracellular parasites, chlamydiae must survive within eukaryotic cells for sufficient time to complete their developmental cycle.

A 2-pyridone-amide inhibitor targets the glucose metabolism pathway of Chlamydia trachomatis. [PDF]

open access: yes, 2014
UnlabelledIn a screen for compounds that inhibit infectivity of the obligate intracellular pathogen Chlamydia trachomatis, we identified the 2-pyridone amide KSK120.
