Nucleotide and deduced amino acid sequences of A. pernix polA (a) and polB (b) genes. The regions used in designing primers for genome walking PCR are indicated by black arrows; grey arrows indicated the primers used in amplifying the structural gene for each polymerase. The regions including the exonuclease motifs (3) and the polymerase motifs (32) are underlined by solid and broken lines, respectively; boldface letters represent putative box A sequences.
