摘要
<jats:p>The nucleotide sequence of a 4.5-kilobase copper resistance determinant from Pseudomonas syringae pv. tomato revealed four open reading frames (ORFs) in the same orientation. Deletion and site-specific mutational analyses indicated that the first two ORFs were essential for copper resistance; the last two ORFs were required for full resistance, but low-level resistance could be conferred in their absence. Five highly conserved, direct 24-base repeats were found near the beginning of the second ORF, and a similar, but less conserved, repeated region was found in the middle of the first ORF.</jats:p>
