Opis

In response to significant new structural information on soluble forms of pore-forming proteins, this book shows how important pore-forming toxin families achieve membrane binding and which structural elements are used for formation of transmembrane pores.

O autorze

Gregor Anderluh is Associate Professor of Biochemistry at the Department of Biology, Biotechnical Faculty, University of Ljubljana, Ljubljana, Slovenia. He and his coworkers are studying protein-membrane interactions and how cellular membranes are damaged by proteins. He is a director of the Infrastuctural Centre for Surface Plasmon Resonance at the University of Ljubljana, where they study molecular interactions and are developing novel approaches on how to study protein binding to membranes. He received his PhD in Biology from University of Ljubljana and did his Postdoctoral at University of Newcastle, United Kingdom. Jeremy Lakey is Professor of Structural Biochemistry at the Institute for Cell and Molecular Biosciences, University of Newcastle, UK and runs an academic research group based loosely on the theme of protein biophysical chemistry with interests in protein toxins, membranes and bionanotechnology. Following a first degree in Zoology, Jeremy completed a PhD in Membrane Biophysics at the University of East Anglia UK, followed by periods at the Centre de Biophysique Moléculaire, Orléans, France; EMBL, Heidelberg, Germany and the EPFL , Lausanne Switzerland. He is currently an editor of the Biochemical Journal and member of the facility access panel for the ISIS pulsed neutron source, UK.
