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 ...

Staphylococcus aureus (S. aureus) causes a wide variety of infections, which are of major concern worldwide. S. aureus produces multiple virulence factors, resulting in food infection and poisoning. These virulence factors include hyaluronidases, proteases, coagulases, lipases, deoxyribonucleases and enterotoxins.

European Biophysics Journal, 2005
While conformational flexibility of proteins is widely recognized as one of their functionally crucial features and enjoys proper attention for this reason, their elastic properties are rarely discussed. In ion channel studies, where the voltage-induced or ligand-induced conformational transitions, gating, are the leading topic of research, the elastic

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 ...

Bacterial signal peptide-independent protein export: HlyB-directed secretion of hemolysin
Seminars in Cell Biology, 1993Bacterial ABC transporter proteins are associated with a great number of cellular processes. While many of the best characterised examples are involved in the import of small molecules into the cell, others mediate export of substrates, especially hydrophilic proteins.

Ornithobacterium rhinotracheale North American Field Isolates Express a Hemolysin-Like Protein
Avian Diseases Digest, 2010Ornithobacterium rhinotracheale is a gram-negative bacterium responsible for the sporadic outbreaks of airsacculitis in poultry, accounting for millions of dollars in losses to the poultry industry annually. Although the organism was originally classified as non-beta-hemolytic, recent North American field isolates of O.

[4] Membrane protein crystallization: Application of sparse matrices to the α-hemolysin heptamer
1997Publisher Summary The three-dimensional crystals of membrane proteins can be divided into two classes: (1) type I crystals, which consist of layers of molecules in which the hydrophobic contacts between the lipid-embedded portions of a protein mediate the intralayer interactions and the hydrophilic contacts between the domains exposed to aqueous ...

All-Atom Molecular Dynamics Simulation of Protein Translocation through an α-Hemolysin Nanopore
The Journal of Physical Chemistry Letters, 2015Nanopore sensing is attracting the attention of a large and varied scientific community. One of the main issues in nanopore sensing is how to associate the measured current signals to specific features of the molecule under investigation. This is particularly relevant when the translocating molecule is a protein and the pore is sufficiently narrow to ...
