This biobrick is a improvement of biobrick BBa_K519010
Usage and Biology
SmtA is a metallothionein which bind to divalent metallic cations such as Zn(II). This SmtA was an improvement of the biobrick BBa_K519010 originally cloned from Synechococcus sp. PCC7942, a cyanobacterial strain. SmtA is a low cys content type II metallothionein. Other team (iGEM11_Tokyo-NoKoGen, 2011-09-30) have previously find SmtA constitutively expressed in E. coli improving its growth at a high Cd(II) concentrationwhen compared to wild type E. coli. This part was designed to eliminate an internal restriction site for PstI, the 98th base was changed G -> A. No residues were changed.
Figure 1: Improved SmtA (BBa_K1620007) compared to BBa_K519010; this new sequence is biobrick compatible due the removal of a PstI restriction site previously present in BBa_K519010.
