Fig. 1. The consensus sequences for the fibroins expressed in the MA glands of
Nephila clavipes and Araneus diadematus, as presented in
Gatsey et al. (Gatsey et al., 2001). Nc-MA-1 is spidroin-1 type and Nc-MA-2 is
spidroin-2 type. Ad-MA-1 and Ad-MA-2 are both spidroin-2 type and were
previously called ADF-3 and ADF-4 by Guerette et al.
(Guerette et al., 1996). The
percentage values at the end of each sequence give the relative size of the
poly-alanine block and the percentage proline in each consensus repeat.
