Figure 3.

Nucleotide and deduced amino acid sequences of the cDNA encoding naat-B (NAAT-A isozyme). The stop codon is indicated by an asterisk (*). The specific probe (probe III) for the 3′-terminal sequence used for genomic Southern hybridization and the putative PLP-binding Lys residue are shaded. There are six core SNGH sequences in the N-terminal region (boxed). Arrowheads show the six introns deduced from the genomic DNA sequence in Figure 8.
