This part is designed to enable Lead Detection in a cell. When Lead (Pb +2) enters the cell, it will couple with the Lead Binding protein, forming a dimer. BBa_I721002 contains only the Lead Binding Protein sequence, and must be combined with a Lead Promoter sequence in ordered to be remotely functional.

Description
This part is designed to enable Lead Detection in a cell. When Lead (Pb +2) enters the cell, it will couple with the Lead Binding protein, forming a dimer. BBa_I721002 contains only the Lead Binding Protein sequence, and must be combined with a Lead Promoter sequence in ordered to be remotely functional.

This sequence was obtained using PCR from the genome of Ralstonia metallidurans. Biobrick cut sites were added using specific primers during PCR.

This part is not known to function. "PbrR691/promoter combinations in presence of lead nitrate give no GFP production and no AHL production compared to control. "

The figure below illustrates the layout of this sequence.

Sequence Layout of I721003


BBa_I721002 contains only the Lead Binding Protein region.

15 planned Lead Promoter and Lead Binding Protein Biobricks

Because of the different coding regions contained in this sequence, the Brown iGEM Team chose 15 different regions of the Pbr691 and PbrR691 sequences to extract. We attempted to create Biobricks from each of these 15 different sequences. Some contained only the PbrR Lead Binding Protein, some contained only the Pbr Promoter, and some parts contained both. The following diagram illustrates these different parts.

Functional Layout of I721003

BBa_I721002 was designed to be a part of the Brown University Cellular Lead detector device. The BBa_I721002 Lead Binding Protein was designed to be attached with part BBa_I721004, the Lead Promoter. This was designed to form a Lead Detection System, to be attached to the Amplification system by Imperial College, (BBa_J37015), with GFP as the output of the device. The schematic for this project is below:
