Part:BBa_K1465205
Carbonic anhydrase (csoS3) of the carboxysome of Halothiobacillus neapolitanus
The carbonic anhydrase from Halothiobacillus neapolitanus converts incoming hydrogen carbonate into carbon dioxide inside the carboxysome. This step is essential for the CO2 fixation.

2018, AHUT-China iGEM team codon-optimized the coding sequence (CDS) of the original part (BBa_K1465205), and linked a histidine tag (His-Tag) fllowing the coding sequence (CDS) then submitted a new one. Part BBa_K2547003.

In 2017 SZU-China iGEM team changed the sequence of original part(BBa_K1465205) and the new part BBa_K2232022 was submited.
Contribution from iGEM2017 SZU-China
We add the RBS of Bacillus subtilis and a segment of signal peptide at the upstream of cds of Carboxysomal Carbonic Anhydrase(csoS3) from Halothiobacillus neapolitanus, in order to achieve the expression and secretion of this part in the B.subtilis WB800. The construction of the shuttle expression-secretion vector_CsoS3 is shown as follow in figure 1.
The new part (BBa_K2232022) was constructed into shuttle expression-secretion vector pP43NMK, and 1% Agarose Gel Electrophoresis of the plasmid verified the correct construction in figure 2.
The crude enzyme solution was obtained from the supernatant of fermentation broth of the Bacillus subtilis including the original strain WB800 and the recombinant WB800_ CsoS3. Since the fact that CA can also catalyze the hydration reaction of ester, which can be used to assay the activity of CA, we conducted measurement on CsoS3 according to a method from Verpoorte JA(1967), and the result(Fig.3) certified that the CsoS3 has high esterase activity.
