摘要：

In Streptomyces ambofaciens, an amplifiable unit of DNA (AUD6) contains two homologous sequences, one located on the right extremity of the AUD (SIR), the other being internal (IHS). This paper presents the molecular analysis of this duplication. The nucleotide sequences are almost identical (95%) and each contains an ORF of about 330 codons, the two ORFs being nearly identical. The two hypothetical proteins, deduced from these sequences, show about 30% identity with different bacterial repressors. They also show a particularly strong similarity (90% identity between the full-length sequences) with hypothetical proteins of Streptomyces lividans 66 encoded by sequences also present on an amplifiable DNA region (AUD1).
