Acetate production construct

Usage and Biology

2 Trancription Units

Design Notes

The coding sequence was domesticated . We removed BsmBI and BsaI sites in order to be compatible with GoldenBraid and MoClo. The sequence is cloned in seva omega1R vectorBBa_K3505010 and has overhangs compatible for GoldenBraid cloning.

Experimental Use and Experience

Before we start producing SCFAs, we needed to optimize our protein expression system.
