Spider silk fibroins can adopt different structural states at high protein concentrations. They are soluble within the spinning dope of the glands, but readily converted into insoluble polymers upon extrusion. A contribution of the C-termini to the maintenance and conversion of these states is suggested by their predicted secondary structures and biochemical behavior in vitro. Special sequence parts endow the C-termini with the capability to promote both the solubility and aggregation of the fibroins depending on the environmental conditions. (c) 2005 Elsevier Inc.
