Usage
Janus is a kind of amphipathic protein which could self-assembly spontaneously. Due to its special properties, we could make many new applications. We use them as substrate to fix antibodies on a high-flux tumor detection chip. Meanwhile, they are used to catch cutinases for plastic degradation. We even make them into a fusion to test if the enhancement could be better. And we use its amphipathicity to achieve protein separation, where they act as a special purification tag, and the system could be as simple as polymer, detergent and water.
Biology
Janus could be produced by filamentous fungi, such as Ascomycetes and Basidiomycetes, and their scientific name is hydrophobin. Many different aspects of fungal development have been attributed to Janus. For example, they are thought to play a role in the formation of aerial hyphae and fruiting bodies. One of the most important features of Janus is that they are able to assemble spontaneously into amphipathic monolayers at hydrophobic–hydrophilic interfaces.
There are two classes of Janus, which are divided by the stability of their self-assembly. sJanus from Trichoderma reesei belongs to Class II. The assemblies of class II Janus can be dissolved in ethanol or sodium dodecyl sulfate or through the application of pressure or lowering of the temperature. We did some mutations to it, and we call it sJanus-m.
