摘要: Motivation The underlying error rate for genomic sequencing sometimes results in the introduction of artificial frameshifts and in-frame stop codons into putative protein encoding genes. Severe errors are then introduced inferred transcripts through mis-translation or premature termination. Results We describe a system screening segments DNA frameshift coding regions. method is based on homology matching using blastx to compare all six reading frames query nucleotide sequence against selected databases. Fragments neighbouring regions united extended laterally define candidate open frames, within which, stops identified. Suitable targets include prokaryotic other intron-free complementary DNAs. As an example its use, we report here two frameshifted ORFs that deviate from original TIGR annotations recently released Helicobacter pylori genome.
