Alignment of Cystatin-like proteins from P. infestans and P. halstedii. The Phytophthora infestans Cystatin-like protein EPIC4 [GenBank:AY935254] was aligned with the putative P. halstedii Cystatin-like protein [GenBank:CB174713]. NT indicates the N-terminus trauncation, L1 and L2 indicate two conserved loop. The asterisk indicates the conserved Tryptophane amino acid within the L2 loop. The potential Peptide signal is also indicated.
