NodC Generator I
The NodC Control Generator with Weak Promoter produces the NodC protein. The NodC protein produces the carbohydrate, chitin.The NodC Generator with Weak Promoter does not produce a lot of the NodC protein. The NodC protein produces chitin.
This part consists of 821 base-pair length. It includes a promoter, 1 ribosome binding site, 1 protein-coding sequence, and a terminator. We used promoter K2832184, a weak promoter from the BIOFAB collection. In addition, we also used a protein-coding sequence from Chitin synthase from Rhiozobium leguminosarum.
This generator was assembled into the pSB1K3 plasmid, and then transformed into E.Coli NEB 5-Alpha. To test if the cells were secreting chitin, The FSU 2021 team used the Chitosan Assay Kit (XAN-5126) available from Cell Biolabs. The manual for this kit contains the protocols for converting chitin to chitosan, along with a protocol for detecting chitosan.
Chitin from the cells was converted into chitosan by reacting with 12.5M NaOH at 95°C for 24 hours. The solution was then neutralized with acetic acid. The assay was then performed on the supernatant of the cell culture.
