AlcR is a gene found in Aspergillus nidulans which encodes for a regulatory protein (Panozzo <i>et al.</i>, 1997). AlcR can bind to the alcA and aldA promoters (PalcA and PaldA, respectively). In the presence both AlcR and ethanol or threonine, genes downstream of these promoters are expressed (Felenbok <i>et al.,</i> 1988).

This construct was built to overexpress alcR, a regulatory protein necessary for the activation of palcA (BBa_K2092002). We acquired all parts from the iGEM distribution kit: a strong promoter and strong RBS combination (BBa_K880005) to maximize protein production, strong RBS (BBa_B0034), alcR (BBa_K2092001), and a double terminator (BBa_B0015) to end transcription. PCR checks and sequencing results from Tri-I Biotech confirmed that our final alcR construct is correct.

AlcR Expression Construct AlcR is a gene found in Aspergillus nidulans which encodes for a regulatory protein (Panozzo et al., 1997). AlcR can bind to the alcA and aldA promoters (PalcA and PaldA, respectively). In the presence both AlcR and ethanol or threonine, genes downstream of these promoters are expressed (Felenbok et al., 1988).


Construct Design LINK

This construct constitutively express alcR, a regulatory protein necessary for the activation of PalcA. We use a strong promoter and strong RBS combination (BBa_K880005) to maximize protein production, the alcR sequence (BBa_K2092001), and a double terminator (BBa_B0015) to end transcription.


PCR Check Results The part was confirmed by PCR using the primers VF2 and VR, as well as sequencing by Tri-I Biotech.
