Fig 5. Determination of the specificity conferring code of ca-activating domains. The primary sequence between core A4 and A5 (see Fig. 3) of nine ca activating domains are aligned by using the Clustal method. Based on the structural data of DhbE, extraction of the 10 residues conferring the substrate specificity leads to the identification of the signature sequence of ca activating A domain. The asterisks define the residues that allow discrimination between DHB and SAL.
