Guinea pig D-amino-acid oxidase cDNA and phylogenetic position.
The nucleotide sequence of cDNA that encodes guinea pig D-amino-acid oxidase (DAO) was determined. The cDNA consisted of 1,399 nucleotides and a poly(A) tail. The cDNA encodes 347 amino acid residues. In contrast to the hamster, rat, and mouse DAOs, guinea pig DAO had the 25th amino acid residue. The homology in amino acid sequences between the guinea pig DAO and the rodent DAOs was not high in comparison to the homology in amino acid sequences between the guinea pig DAO and DAOs of humans, pigs and rabbits. The phylogenetic position of the guinea pig varied depending on the source of sequences (amino acids or nucleotides) and the methods of phylogenetic tree construction. These results suggest that the guinea pig is not a simple rodent.
