Ribulose-1,5-biphosphate carboxylase/oxygenase catalyzes the first reaction of the Calvin cycle, converting the combination of Ribulose-1,5-biphosphate (RuBP) and carbon dioxide to two 3-phosphoglycerate molecular. The rbcL part encodes the large subunit of the RubisCO enzyme, which also contain the active site of the enzyme. In our carbon fixing pathway, the RubisCO enzyme is the most important enzyme catalyzing the reaction of RuBP and CO2.
The rbcL gene is from cynobacteria Synechococcus elongatus PCC 7002. We designed the LacI regulated promoter (BBa_R0010) for the gene and cloned gene in W3110. We also coden optimized the gene to ensure successful expression. However, the activation of RubisCO will be maximize with the binding of the RbcS subunit. To get more information, see our composite part: BBa_K2762012.
Expression in E. coli
We did two experiment to confirm the expression of this part. First we inserted the part on pSB1C3 and transformed the plasmid into DH5 alpha. We extracted the plasmid after the the formation of the colony and screened the consruction by enzyme digestion. Second, we cloned the plasmid into W3110. We than did the SDS-PAGE to confirm the present of the RbcL.
