Our System

Data for our Favourite New Parts

Main Page - GAL galactose-inducible yeast promoter, BBa_K517000: Promoter can be induced when exposed to galactose in the absence of glucose. We characterized this part by placing a reporter GFP gene downstream of the promoter and determined that GFP expression was up-regulated when the yeast was shifted to galactose media.

Main Page - GPD constitutive yeast promoter, BBa_K517001: Promoter for constitutively high expression. We characterized this part by placing a reporter GFP gene downstream of the promoter and determined that GFP was expressed regardless of whether the yeast was in glucose, raffinose or galactose media.

Main Page - Alpha-Pinene Synthase Gene, BBa_K517002: The (-)-a-pinene synthase (PsTPS-Pin) was isolated from Sitka spruce and converts geranyl pyrophosphate to 83.4%(-)-alpha-pinene, 12.6%(-)-beta-pinene, 2.1% Linalool, 1.0% (-)-beta-phellandrene, 0.4% Camphene, and 0.4% myrcene. We characterized it by expression in C41 DE3 E. coli followed by a His-tag purification. The purified enzymes were assayed in vitro with GPP and sent for GC-MS, which confirmed alpha- and beta-pinene as products.

Data for Pre-Existing Parts

Experience - Limonene Synthase Composite + Lac promotor, BBa_K118025 (Edinburgh, iGEM 2008): We expressed this part in C41 E. coli that possesses a pRARE plasmid that enables it to translate proteins with rare codons. The limonene synthase was purified from a culture and subjected to an enzymatic assay for its ability to synthesize limonene monoterpene from GPP substrate. GC-MS analysis showed that limonene was present in the sample where GPP was added. In contrast, the control without GPP did not contain limonene.

Experience - Yeast GAL1 Promoter, BBa_J63006: We characterized this part by placing a reporter GFP gene downstream of the promoter and determined that GFP expression was up-regulated when the yeast was shifted to galactose media.

Experience - E. coli Isopentenyl Diphosphate Isomerase, BBa_K115056 (TU Delft 2008): We sequenced this part using the VF2 and VR primers and found that the sequence between the original EcoRI and PstI restriction enzyme sites (1) did not contain the XbaI or SpeI sites and (2) was not homologous to any part of the IDI gene. We recommend that this part is removed from the registry and taken off distribution.

Data for our Other Parts

Main Page - Beta-Pinene Synthase Gene, BBa_K517003:
The (-)-b-pinene synthase (PsTPS-Pin2) synthase is a monoterpene synthase isolated from Sitka spruce converts geranyl pyrophosphate to 70.5%(-)-beta-pinene, 29.5%(-)-alpha-pinene. (-)-b-pinene synthase has been previously characterized by expression in C41 DE3 E. coli followed by a His-tag purification. The purified enzymes were assayed in vitro with GPP and sent for GC-MS. The iGEM team also aims to characterize the beta-pinene in vivo in S. cerevisiae yeast, which will be sent for GC-MS.

Main Page - ERG20, BBa_K517004: An essential gene in yeast encoding an enzyme of the mevalonate pathway that produces FPP and GPP from I-PP and DMA-PP.

Main Page - erg20-2, BBa_K517005: A mutant of the ERG20 gene; K197E substitution. The encoded mutant protein produces 25% FPP and 75% GPP instead of 75% FPP and 25% GPP compared to the wild type Erg20.
