Fig. 4From: The Duffy binding protein (PkDBPαII) of Plasmodium knowlesi from Peninsular Malaysia and Malaysian Borneo show different binding activity level to human erythrocytesSequence alignment of PkDBPαII from Peninsular Malaysia and Malaysian Borneo and the reference P. knowlesi strain H. Amino acid residues identical to those of the reference strain H (GenBank Accession No. M90466) are marked by dots. The amino acid changes and 12 highly conserved cysteine residues are highlighted in cyan and yellow, respectively. Amino acid residues, Y94, N95, K96, R103, L168 and I175, which have been identified previously as essential for binding with DARC [33, 34], are in red boxes Back to article page
