Cup1 for E. coli
Cup1 is a gene in Saccharomyces cerevisiae that encodes for metallothionein (MT), a metal-binding protein.
Usage and Biology
Metallothionein plays an important role in intracellular metal distribution and the protection of the cell against heavy metal toxicity and oxidative stress. MT has a high metal binding affinity. Due to its role in metal reduction, previous studies have investigated its potential for the production of metal nanoparticles (NPs). This was done by integrating MT in various biological platforms.1 Thus, we expressed cup1 in an engineered Escherichia Coli (E. coli), with the aim of producing gold and silver NPs.
Design
The sequence was codon optimized for E.coli. Two overhang sequences with the restriction enzymes BamHI and NdeI were designed and added to the sequence. This part is therefore compatible with vectors that have those two restriction sites. In the Binanox project, the vector pET-16b was used.
