Abstract(s) :

(Anglais) Cupriavidus necator B9, a new metal-resistant strain, carries a 19 copper resistance genes cluster (cop cluster) of particular interest because of its synteny with the cop operon present in Cupriavidus metallidurans CH34. Surprisingly, the strain B9 carries four copies of copH gene contrary to the strain CH34 which has only one. Furthermore, mass spectrometry experiment on C. necator B9 shew the overabundance of the 4 corresponding proteins in a metal-contaminated medium. These proteins share a similar structural C-terminal sequence but differ in their functional N-terminal part. Therefore, further analyses are required to understand specific role of each CopH.
