Figure 4
(a) The crystal packing of internalin C molecules viewed down the twofold axis, showing the open packing of the molecules in the crystal lattice when viewed in this direction. The figure shows that it is the Ig-like domain that is involved in the crystal contacts. The cap domain is involved in an association across the twofold involving Pro42 and Leu68, but there are few contacts involving the LRR domain. (b) A closer view of the aromatics involved in the packing of the Ig-like domains in the crystal. |
