Nucleotide and deduced amino acid sequences of EuIPI . EuIPI (Accession No. AB041629) consists of 1028 bp with a 675-bp ORF encoding a protein with 224 amino acid residues. Numbers of nucleotide sequence and amino acid sequence are indicated on left and right, respectively. Start codon (ATG) is underlined; stop codon (TAG) is marked with *. Broken lines indicate four highly conserved regions of IPIs. Residues critical for catalytic activity of the enzyme are highlighted in red bold font. Boxes show the conserved C (cysteine) motif and the conserved E (glutamic acid) motif.
