Hydrophobins: proteins with potential

Hydrophobins are self-assembling proteins of fungal origin. Their ability to self-assemble into an amphipathic membrane is of interest for many different applications, ranging from medical and technical coatings to the production of proteinaceous glue and cosmetics. Assembled hydrophobins can modify surface characteristics, thus controlling the binding properties of the surface; for example, enzymes can be actively and non-covalently immobilized on electrode surfaces and medical coatings can be improved for biocompatibility. Over the past few years research on hydrophobins has contributed to a better understanding of the self-assembly process and is generating more handles to control and manipulate the process. This knowledge could have an immediate effect on production levels, which are not yet adequate, and provide the boost needed for hydrophobins to reach their full potential.
