Evidence for a Putative Isoprene Reductase in Acetobacterium wieringae

“…Export of heavy metals from cells can be performed by a diverse number of mechanisms ( 96 ). While no Ni-specific metal exporters ( 97 ) were detected in the genome of A. wieringae ISORED-2, three P-type IB ATPases were found: ISORED2_00744 ( cadA : Cd 2+ , Zn 2+ , and Co 2+ ), ISORED2_02650 ( copA : Cu + ), and ISORED2_03115 ( ziaA : Zn 2+ ). Members of the P-type ATPase subfamily IB normally transport soft Lewis acids but often have limited specificity.…”
