Composite Parts
We constructed 4 composite parts during this years iGEM competition. Three of them were made by attaching a promoter (with or without a ribosome binding site) in front of another part. The last was an RBS coding sequence fusion that we had synthesised by IDT.
BBa_K2718006
Methionine gamma-lyase (MGL) catalyzes the conversion of l-methionine to methanethiol, the oxidation of methanethiol then produces first DMDS (Dimethyl disulfide) and then DMTS ( Dimethyl trisulfide). The composite part BBa_K2718006 is made from BBa_K2718005, an RFC 10 compatible part that we derived from BBa_K1493300 using a PCR to add a C-terminal histidine tag, preceded by the BBa_R0011, an IPTG inducible promoter part. To test the activity of BBa_K2718006 we produced and purified the his-tagged protein and used DTNB to measure the enzyme activity. DTNB reacts with the released thiol group [1].
