Abstract A cDNA encoding mouse metallothionein was cloned into the shuttle vector pUC303, creating a translational fusion with the bacterial chloramphenicol acetyltransferase gene. The resulting fusion protein has been expressed in the cyanobacteriumSynechococcus PCC7942. Cyanobacterial transformants expressed mouse metallothionein-specific mRNA species as detected by RNA slot blots. In addition, the transformants expressed a unique cadmium ionbinding protein corresponding to the predicted size of the mouse metallothionein fusion protein. Expression of this fusion protein conferred a two-to five-fold increase in cadmium ion tolerance and accumulation onSynechococcus PCC7942.
