摘要：

The genome of Melioribacter roseus, one of the two members of the recently described phylum Ignavibacteriae, was screened for genes encoding proteins associated with copper transport or containing copper as a cofactor, and the effect of Cu2+ concentration in the medium on M. roseus growth was investigated. Genomic analysis revealed a variety of copper-containing oxidoreductases in this facultative anaerobe. Three ATPases responsible for copper transport were identified. One of them (MROS_1511) is probably involved in the assembly of copper-containing cytochrome c oxidase, while two others (MROS_0327 and MROS_0791) probably carry out a detoxification function. The presence of several copper-containing oxidoreductases and copper homeostasis systems in M. roseus is in agreement with the previously hypothesized origin of the phylum Ignavibacteriae from an aerobic ancestor common with Bacteroidetes and Chlorobi.
