Pore-Forming Bacterial Protein Hemolysins (Cytolysins)
Critical Reviews in Microbiology, 1991Protein toxins forming pores in biological membranes occur frequently in Gram-positive and Gram-negative bacteria. They kill either bacteria or eukaryotic cells (at most, a few seem to act on both groups of organisms). Most of the toxins affecting eukaryotes have clearly been shown to be related to the pathogenicity of the producing organisms.

Hemolysin toxin produced and secreted by pathogenic Escherichia coli is one of a family of cytolytic, structurally homologous protein toxins known as RTX (repeats in toxin) toxins. RTX toxins are products of a gene cluster, CABD. The A gene product, nontoxic hemolysin (proHlyA), is made toxic by posttranslational fatty acylation of two internal lysine ...

Unfolding and Translocation of Proteins Through an Alpha-Hemolysin Nanopore by ClpXP
2020Proteins present a significant challenge for nanopore-based sequence analysis. This is partly due to their stable tertiary structures that must be unfolded for linear translocation, and the absence of regular charge density. To address these challenges, here we describe how ClpXP, an ATP-dependent protein unfoldase, can be harnessed to unfold and ...

Hemolysins: Pore-forming proteins in invertebrates
Experientia, 1990Invertebrates possess lytic molecules which lyse vertebrate erythrocytes. In all the species studied so far, hemolytic activity depends on proteins which possess a wide range of reactivity. It is generally calcium-dependent and heat-labile, although calcium-independent and heat-stable hemolysins have also been detected.

Despite the recent global increase in fatal endemic outbreaks of proliferative enteropathy (PE) caused by the obligate intracellular bacterium Lawsonia intracelluralis (LI) in the swine industry, development of effective prevention strategies or immunodiagnostic tests has been delayed due to the difficulty of cultivating this pathogen in vitro ...

Secretion of Escherichia coli hemolysin is mediated by a sec-independent pathway which requires the products of at least three genes, hlyB, hlyD and tolC. Two regions of HlyD were studied. The first region (region A), consisting of the 33-amino acid, C-terminal part of the HlyD protein, is predicted to form a potential helix-loop-helix structure.

Pleurotus and Agrocybe hemolysins, new proteins hypothetically involved in fungal fruiting
Biochimica et Biophysica Acta (BBA) - General Subjects, 2002Novel hemolytic proteins, ostreolysin and aegerolysin, were purified from the fruiting bodies of the edible mushrooms Pleurotus ostreatus and Agrocybe aegerita. Both ostreolysin and aegerolysin have a molecular weight of about 16 kDa, have low isoelectric points of 5.0 and 4.85, are thermolabile, and hemolytic to bovine erythrocytes at nanomolar ...

Thermostable direct hemolysin (TDH) is a possible virulence factor produced by Vibrio parahaemolyticus. Although TDH has a variety of biological activities, including hemolytic activity, the biochemical mechanism of action remains uncertain. Here we analysed biochemical events, especially phosphorylation, caused by TDH in erythrocytes, and found that ...
