 The nucleotide and deduced aa sequences of Bombyx mori protein disulfide isomerase (bPDI) complementary deoxyribonucleic acid (cDNA). The cDNA sequence of this bPDI gene was submitted to GenBank under accession number AF325211. The predicted amino acid sequence (single-letter abbreviations) is shown below the nucleotide sequence within the open reading frame. Two activation domains, EFYAPWCGHCKSLAP (aa 47–61) and EFYAPWCGHCKQLVP (aa 389–403), are indicated by shaded areas, and the endoplasmic reticulum retention signal (KDEL) is indicated in bold. The translation start and stop codons are indicated by asterisks. The underlined nucleotide sequences indicate the putative polyadenylation signal and poly(A) tail, respectively
