Abstract

We describe the biosynthesis and characterization of protein materialscomprised of two distinct self-assembling domains (SADs): elastin (E) foundin tissue for its elastic properties and cartilage oligomeric matrix proteincoiled-coil (COMPcc, C) predominantly locatedin joint and in bones. Based onearlier studies on protein block polymers comprised these two SADs,orientation and number of blocks play a crucial role in the overallstimuli-responsive supramolecular assembly behavior. Here we fabricate arange of EnC and CEn block polymers in which the Edomain is systematically truncated to explore the effects of the E domain onthe overall physicochemical behavior.
