Dependence of the normalized radius of gyration for stickerspacer IDRs, in which spacers are glycineserine repeats and stickers are one or more tyrosine residues. The normalized radius of gyration is calculated as the ALBATROSS R g divided by the R g expected for a sequencematched version of the protein behaving as a Gaussian chain (the analytical Flory random coil (AFRC) model) 50 . Each sequence here contains eight stickerspacer repeats. Each repeat contains spacer regions (glycineserine dipeptide repeats) that vary in length from 2 to 120 residues and sticker regions (polytyrosine repeats) that vary in length from 0 to 8 tyrosines.
