Influence of Heavy Metals on Microbial Growth Kinetics Including Lag Time: Mathematical Modeling and Experimental Verification.
PMID: 19496634. This looks like an interesting model to study - esp given the specific ways Zn and Cu affect halo growth
Removal of multi-heavy metals using biogenic manganese oxides generated by a deep-sea sedimentary bacterium - Brachybacterium sp. strain Mn32.
PMID: 19383675. Apparently oxides of Mn(II) can sequester Zn, maybe copper. Check to see how Mn(II) specific resistance is differentially expression during Zn/Cu stress.
Oh, hell yes ...
A P-type ATPase importer that discriminates between essential and toxic transition metals.PMID: 19264958. A heavy metal importer with specificity to Cu and Zn is identified in Pseudomonas aeruginosa Q9I147. There are several importers described or referenced here with specificities only for Cu or Zn. Get protein sequences and blast against the Halo proteome.
Last, worthwhile to review. I might have this one already
