Fig. 3

Amino acid sequence of the complete Uloborus diversus pseudoflagelliform spidroin, showing the N-terminal, repetitive, and C-terminal regions. Abundant amino acids are highlighted as follows: alanine (red), serine (purple), glycine (green), glutamine (blue), proline (cyan), and glutamic acid (orange). Each ensemble repeat is labeled on the right by their repeat type classification (see Additional file 3: Figure S2). Recurring, higher level pattern of repeats (R1, R2, R3, R4) are indicated by grey boxes
