Substrate specificity and the effect of calcium on Trypanosomabrucei metacaspase 2 [PDF]

open access: yesThe FEBS Journal, Volume 280, Issue 11, Page 2608-2621, June 2013., 2013
Metacaspases are cysteine peptidases found only in yeast, plants and lower eukaryotes, including the protozoa. To investigate the extended substrate specificity and effects of Ca<sup>2+</sup> on the activation of these enzymes, detailed ...

The Role of Proteinase-Activated Receptors 1 and 2 in the Regulation of Periodontal Tissue Metabolism and Disease [PDF]

open access: yesJournal of Immunology Research, Volume 2017, Issue 1, 2017., 2017
Proteinase-activated receptors 1 (PAR1) and 2 (PAR2) are the most highly expressed members of the PAR family in the periodontium. These receptors regulate periodontal inflammatory and repair processes through their activation by endogenous and bacterial ...

Intracellular Porphyromonas gingivalis Promotes the Proliferation of Colorectal Cancer Cells via the MAPK/ERK Signaling Pathway

open access: yesFrontiers in Cellular and Infection Microbiology, 2020
Porphyromonas gingivalis (P. gingivalis) is a keystone pathogen in periodontitis. However, several clinical studies have revealed an enrichment of P. gingivalis in the stool samples and colorectal mucosa of colorectal cancer patients.

Contribution of proteases to the hallmarks of aging and to age‐related neurodegeneration

open access: yesAging Cell, Volume 21, Issue 5, May 2022., 2022
Proteases are a large family of proteolytic enzymes located in all cell compartments and in the extracellular space. Proteases impact all hallmarks of cellular and tissue aging, and the onset and progression of age‐related diseases including neurodegeneration.

A diverse uncultivated microbial community is responsible for organic matter degradation in the Black Sea sulphidic zone

open access: yesEnvironmental Microbiology, Volume 23, Issue 6, Page 2709-2728, June 2021., 2021
Summary Organic matter degradation in marine environments is essential for the recycling of nutrients, especially under conditions of anoxia where organic matter tends to accumulate. However, little is known about the diversity of the microbial communities responsible for the mineralization of organic matter in the absence of oxygen, as well as the ...

Dipeptidyl‐peptidases: Key enzymes producing entry forms of extracellular proteins in asaccharolytic periodontopathic bacterium Porphyromonas gingivalis

open access: yesMolecular Oral Microbiology, Volume 36, Issue 2, Page 145-156, April 2021., 2021
Abstract Porphyromonas gingivalis, a pathogen of chronic periodontitis, is an asaccharolytic microorganism that solely utilizes nutritional amino acids as its energy source and cellular constituents. The bacterium is considered to incorporate proteinaceous nutrients mainly as dipeptides, thus exopeptidases that produce dipeptides from polypeptides are ...

Identification of the active site of legumain links it to caspases, clostripain and gingipains in a new clan of cysteine endopeptidases

open access: yesFEBS Letters, 1998
We show by site‐directed mutagenesis that the catalytic residues of mammalian legumain, a recently discovered lysosomal asparaginycysteine endopeptidase, form a catalytic dyad in the motif His‐Gly‐spacer‐Ala‐Cys. We note that the same motif is present in the caspases, aspartate‐specific endopeptidases central to the process of apoptosis in animal cells,

Zebrafish as a new model to study effects of periodontal pathogens on cardiovascular diseases. [PDF]

open access: yes, 2016
Porphyromonas gingivalis (Pg) is a keystone pathogen in the aetiology of chronic periodontitis. However, recent evidence suggests that the bacterium is also able to enter the bloodstream, interact with host cells and tissues, and ultimately contribute to

Synthesis of Sphingolipids Impacts Survival of Porphyromonas gingivalis and the Presentation of Surface Polysaccharides [PDF]

open access: yes, 2016
Bacteria alter the biophysical properties of their membrane lipids in response to environmental cues, such as shifts in pH or temperature. In essence, lipid composition determines membrane structure, which in turn influences many basic functions, such as

Clan CD of cysteine peptidases as an example of evolutionary divergences in related protein families across plant clades [PDF]

open access: yes, 2010
Comparative genomic analyses are powerful tools that can be used to analyze the presence, conservation, and evolution of protein families and to elucidate issues concerning their function.
