pPCK1 S. cerevisiae promoter
| Types | DnaRegion |
| Roles | Regulatory promoter |
| Sequences | BBa_K2030001_sequence (Version 1) |
Description
The upstream regulatory sequence to the gene PCK1, coding for Phosphoenolpyruvate carboxykinase. This promoter is induced by glycerol, acetate and ethanol (10x) [1].Notes
The complete sequence of Saccharomyces cerevisiae S288c chromosome XI (Genbank accession number BK006944) was used to design primers for amplification of this promoter.FW: gccgcttctagagTCGTTCGTTGTACGTACATTTAC
RV: ttcttcctgcagcggccgctactagtaGTTGTTATTTTATTATGGAATAATTAGTTGC
The primers were designed to anneal at 63 degrees (although PCR worked better at 61), using Phusion High-Fidelity DNA Polymerase.
The uppercase nucleotides hybridizes with the template and the lowercase nucleotides contains the overhang. The overhang in the FW primer contains the last 13 bp of the prefix, which includes 6 protective bases before the XbaI site to ensure efficient cutting. The overhang in the RV primer contains the suffix with additional 6 protective bases to ensure efficient cutting with PstI.
For assembly of this biobrick, the vector pSB1C3 (BBa_J04450) was cut with XbaI and PstI and purified from gel. The PCR product of pPCK1 was cut with XbaI and PstI and spin column purified. The two pieces was ligated and chemically transformed into E. coli DH5alpha and plated on LB + chloramphenicol. False positive colonies are red. White colonies were restreaked on LB + chloramphenicol and their plasmids extracted using miniprep. The plasmids were verified by digestion with XbaI and PstI, resulting in two bands: 2044 (vector) and 797 (pPCK1). The biobrick was then sent for sequencing for further verification.
