Figure 1From: Two RND proteins involved in heavy metal efflux in Caulobacter crescentus belong to separate clusters within proteobacteriaSchematic representation of the czr and ncz loci. The czr locus includes six predicted ORFs (CCNA_02805 to CCNA_02811) that probably constitute a putative operon. The putative promoter regions are indicated by bent arrows, upstream of CCNA_02805 (Pczr), CCNA_02806 (Pczr*), and CCNA_02812. The ncz locus includes a putative operon containing three ORFs (CCNA_02471 to CCNA_02473), transcribed from the Pncz promoter. The percentages of amino acid identity between each paralog are indicated by two-way arrows.Back to article page
