Purified proteins were examined in a transmission electron microscope, JEM 100CXII (JEOL, Tokyo, Japan). For atomic force microscopy, an Integra Prima microscope and Nova SPM software (NT-MDT, Moscow, Russia) were used. Scanning was performed in semicontact mode using a 35 nm gold cantilever, NSG01 (NT-MDT). The protein sample was applied to a sapphire substrate, coated with mica and dried at room temperature. PBS was used as a negative control.
