Abstract
Genomic DNAs encoding the horseradish peroxidase (HRP) isozymes, prxC2 and prxC3, were cloned and sequenced. By comparing the sequences of the HRP isozyme-encoding genes, prxC1a and prxC1b and their cDNA [Fujiyama et al., Eur. J. Biochem. 173 (1988) 681-687], , it was concluded that prxC2 and prxC3 consisted of four exons and three introns as in the prxC1 gene family. The position of introns in coding regions were the same in all four prx genes. Genes prxC2 and prxC3 coded for 347 and 349 amino acid (aa) residues, respectively, including putative signal sequences at the N termini. In the flanking regions of both genes, putative promoters and polyadenylation signals were found. Nucleotide sequence homology in the coding region was 71% between prxC1a and prxC2, and 66% between prxC1a and prxC3. The aa sequence homologies in plant and microbial peroxidases were compared.Entities:
