title: Evidence for the possible existence of a remnant L-gulono-gamma-lactone oxidase (GULO) gene in a teleost genome.
abstract: DNA fragments related to the cloudy catshark Scyliorhinus torazame L-gulono-gamma-lactone oxidase (GULO) cDNA were detected in a distant fish species. Although the Southern hybridization pattern was more distinct in species with active GULO, DNA fragments related to the GULO gene were also discovered in the common carp Cyprinus carpio. Additionally, in the common carp, inter-individual variation of the hybridization pattern was observed. Regular screening of available teleost fish gene libraries did not reveal GULO related DNA sequences.
