The major ampullate fiber of both Nephila clavipes and Argiope aurantia is composed of two different proteins, MaSp1 and MaSp2. Each of these proteins has a highly conserved pattern of silk-associated amino acid motifs. The GPGXX motif is the only source of proline and is unique to MaSp2. On the basis of the percent of proline, Nephila clavipes major ampullate silk was calculated to consist of 19% MaSp2 and 81% MaSp1, while Argiope aurantia was calculated to have a significantly higher MaSp2… CONTINUE READING
