pVHb-HAO-Cyt

Device with VHb promter. For specific characterization of the HAO-Cyt coding sequence combination, refer to pBAD-HAO-Cyt(https://parts.igem.org/Part:BBa_K2272020). For characterization of pVHb, refer to https://parts.igem.org/Part:BBa_K2272000.

Usage and Biology

An improved version of https://parts.igem.org/Part:BBa_K1067002 and https://parts.igem.org/Part:BBa_K1067004 by combining the two coding sequences, which were suppose to work hand in hand, together. The VHb promoter was inserted to regulate the nitrification circuit expression under certain hypoxic conditions usually found in Sewage tanks. The homolog developed by DTU-Denmark used what we believed to be an improper coding sequence for a one of the subunits, HAO-B. HAO-B is a putative protein, that at the time may not have been believed to be significant. However, after reviewing the sequence registered in the BLAST database, we believed that HAO-B played a fundamental role in the mechanism of HAO. Since the two parts work hand in hand to nitrify ammonium, we improved the parts from DTU-Denmark by combining the two parts, inserting condionally inducible promoters, and using signal peptides to transport the enzymes to their designated location in the cell.
