Hydrophobins are small proteins that function in the growth and development of fungi. The structures of class II hydrophobins HFBI and HFBII from Trichoderma reesei were studied using grazing incidence X-ray diffraction. HFBI was weakly ordered but HFBII formed a highly crystalline coating on water surface. Change from monoclinic to hexagonal structure was observed as the sample dried. The three-dimensional structures differed from the oblique two-dimensional structures observed in Langmuir-Blodgett monolayers of both HFBI and HFBII by atomic force microscopy.
