Comparison of amino acid sequences of oPRP1 and oPRP2 with phylogenetically neighbouring PRPs. Residues identical to oPRP1 and oPRP2 are shown by black hyphens, residues present only in oPRP2 by pink hyphens, and residues present only in oPRP1 by blue hyphens. The sequence gaps are shown by dots. The amino acid sequences were aligned with the help of Clustal W 1.83 on the DDBJ web site. The arrow indicates the putative primary cleavage site of the signal peptide of oPRP1 or oPRP2. The potential N-glycosylation site is underlined in purple.
