(A) Amino acid sequences of recombinant ErpX (rErpX) and the truncated derivatives of ErpX used in these studies. The 55 amino acids deleted from rErpX17 are indicated by dots. (B) Predicted order/disorder of wild-type ErpX. A PONDR score above 0.5 predicts protein disorder; a score below 0.5 predicts order. The laminin-binding region in the centre of ErpX, as identified through use of variant proteins rErpX15, rErpX16 and rErpX17, is predicted to be extremely disordered in the absence of bound ligand.
