EFE + Terminators

2-oxoglutarate oxygenase/decarboxylase is an Ethylene Forming Enzyme (EFE) that catalyze Ethylene biosynthesis from 2-oxoglutarate. This enzyme was firstly purified from Pseudomonas Siringae pv. phaseolicola PK2, a 2-oxoglutarate-dependent ethylene producing bacterium [1].
This part was cloned by the iGEM Trento 2013 team for the creation of an aerobically engineered pathway for the control of fruit ripening. The part has been successfully operated while controlled by AraC-pBAD in pSB1C3 (BBa_K1065001) using E.coli as chassis. Further information about this part and its characterization can be found in the iGEM Trento 2013 wiki.

Please note that this part has a modified Prefix and Suffix compatible to RFC25 (Freiburg Assembly). Check the design section for more information.

Usage and Biology

The enzyme was thoroughly studied by many reasearch groups. It was purified and characterized with an in vitro test [2]. It was then transformed and ectopically expressed in E.coli [3] and in Synecocystis sp [4].

Safety

This part produces ethylene, a compound that can be inflammable at a concentration between 2.7 to 36%. We characterized this part under the control of an AraC-pBAD promoter. With a air volume/culture volume ratio = 4, we detected about 200 ppm of Ethylene. This concentration is not dangerous and not inflammable. However we suggest to manage this part carefully. (See BBa_K1065001 for more details.)

Please head over to K1065001 for documentation on characterization of this Part.
