The oligomeric state of fatty acid hydroperoxide lyase (HPL), of molar mass ∼55 kDa is uncertain and it has been reported as a trimer or tetramer in vivo. The enzyme has been found to be bi-functional and is active even in the absence of detergent. The association with detergent is known to stabilise the binding of the enzyme to its substrate and the enzyme is more active. No high resolution structure...
The pathogenically important cholesterol-binding pore-forming bacterial ''thiol-activated'' toxins (TATs) are commonly believed to be monomeric in solution and to undergo a transition on membrane binding mediated by cholesterol to an oligomeric pore. We present evidence, gained through the application of a number of biochemical and biophysical techniques with associated modelling, that the TAT from...
