C. metallidurans lead binding protein - pbrD

This part contains coding sequence of Cupriavidus metallidurans CH34 lead binding protein (pbrD, Gene ID: 3170401, Uniprot: Q58AJ8) codon-optimized for Escherichia coli Nissle 1917. Pb(II) resistance was early recognized to be located on pMOL30, one of the two plasmids found in Cupriavidus metallidurans CH34 [1]. The pbrD gene encodes a Pb(II)-binding protein which is essential for functional lead sequestration. When Pb(II) enters the cytoplasm, it can be bound by the pbrD protein, which may function as a chaperone for Pb(II) and cells lacking pbrD show a decreased accumulation of Pb(II) and this accumulation may protect against free exported Pb(II) [3]. The part was evaluated in the composite parts (Part:BBa_K3282005)and (Part:BBa_K3282007) expressed in pUC19 backbone. The composites have the same RBS (Part:BBa_J61109) and terminators (Part:BBa_B0012) with two different promoters T7 (Part:BBa_I719005) and Tac (Part:BBa_K3282006). The four composite parts were tested to determine their Lead accumulation capability.

Pb(II) resistance was early recognized to be located on pMOL30, one of the two plasmids found in Cupriavidus metallidurans CH34 (1). The pbrD gene encodes a Pb(II)-binding protein which is essential for functional lead sequestration. When Pb(II) enters the cytoplasm, it can be bound by the PbrD protein, which may function as a chaperone for Pb(II) and cells lacking PbrD show a decreased accumulation of Pb(II) and this accumulation may protect against free exported Pb(II)(2).
