Aspergillus nidulans, sequence found through
P<i>alcA</i> is one of the strongest inducible promoters in <i>Aspergillus nidulans</i> commonly used to overexpress proteins [1]. It has been shown that P<i>alcA</i> promoter is also functional in monocotyledonous plant sugar cane [2] and <i>Escherichia coli (E.coli)</i>[3]. Its transcriptional activation is dependent on the binding of its positive transcriptional regulator AlcR with various substrates that employ a hydroxyl group, for example ethanol and threonine. The native P<i>alcA</i> consists of 3 AlcR binding sites. The number and position of the AlcR binding sites on the P<i>alcA</i> are crucial in determining its transcriptional activation strength. It has also been shown that each AlcR target in the P<i>alcA</i> contributes differently to the activation of the downstream protein expression [1].
This part is a variant of P<i>alcA</i> <a href=http://parts.igem.org/Part:BBa_K2092002>(BBa_K2092002)</a>. In contrast to the native construct (three AlcR binding sites <i>abc</i>), this variant consists only two binding sites <i>bc</i>. Previous study on sugarcane has shown that there is a 70% decrease in promoter strength for P<i>alcA</i> with only binding sites <i>bc</i> [2]. This finding, however, has not been verified using <i>E.coli</i> as a chassis. This then forms the very basis of our project.

Acropora millepora
This chromoprotein from the coral Acropora millepora, amilCP, naturally exhibits strong color when expressed. The protein has an absorbance maximum at 588 nm giving it a blue/purple color visible to the naked eye, thereby requiring no instruments to observe. The strong color is readily observed in both LB or agar culture, in less than 24 hours of incubation.

Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. <p>No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.

This chromoprotein, amilCP, naturally exhibits very strong color when expressed. The color is blue/purple and is visible to naked eye, thereby requiring no instruments to observe. This DNA was provided by Jeffrey Miller at UCLA. It was made BioBrick-compatible after removal of one illegal internal restriction site (EcoRI).

<i>Aspergillus nidulans</i>. The promoter was first characterized by ?, codon optimized for E.coli by Thermo Fischer Scientific and synthesized by IDT. The construct was assembled using the 3A BioBrick Assembly Method as recommended by iGEM.
PalcA is one of the strongest inducible promoters in Aspergillus nidulans commonly used to overexpress proteins [1]. It has been shown that PalcA promoter is also functional in monocotyledonous plant sugar cane [2] and Escherichia coli (E.coli) [3]. Its transcriptional activation is dependent on the binding of its positive transcriptional regulator AlcR with various substrates that employ a hydroxyl group, for example ethanol and threonine.
The native PalcA consists of 3 AlcR binding sites. The number and position of the AlcR binding sites on the PalcA are crucial in determining its transcriptional activation strength. It has also been shown that each AlcR target in the PalcA contributes differently to the activation of the downstream protein expression [1]. In contrast to the native construct (three AlcR binding sites abc), this variant consists only two binding sites bc. Previous study on sugarcane has shown that there is a 70% decrease in promoter strength for PalcA with only binding sites bc [2].
This part allows detection of ethanol by coupling it with another composite part, <a href="http://parts.igem.org/Part:BBa_K2092008"> BBa_K2092008</a>, which constitutively expresses its transcription factor, AlcR. Blue color development can be seen in presence of ethanol.
