Profile
Name: ChBD3(CBM2)
Gene length: 341 bp
Source: Thermococcus kodakarensis KOD1 (5DHE)
Properties:
ChBD3(CBM2) consists of two catalytic domains and three binding domains (ChBD1, ChBD2, and ChBD3). ChBD2 and ChBD3 can bind to both chitin and cellulose. The spacing of the side chains of the three tryptophan residues on the molecular surface is equivalent to twice the length of the chitin lattice [1]. CBM2-encoded protein has a special affinity for chitin, which is another main component of the fungal cell wall, allowing its binding to fungal cells with the presence of chitin.
Usage and Biology
There are few studies on ChBD3, with most research focusing on its binding domain characteristics. Some studies examine the effect of ChBD3 and cellulose on each other's binding efficiency [2]. We expanded the application of ChBD3 by utilizing its specific binding characteristics with chitin for fungal detection.
Cultivation, Purification, and SDS-PAGE
Both gene sequences were amplified by PCR, confirmed by bands of approximately 300 bp and 500 bp on the electrophoretic gel. The gene length of ChBD3(CBM2) was 341 bp, indicating successful amplification of the target band. Figure 1 shows that the plasmid was successfully linearized.
Figure 2 represents the purified protein. The ChBD3(CBM2) is 35.9 kDa. In Figure 3, the bands corresponding to CBM2-mcherry proteins, ranging from 34 kDa to 43 kDa, are notably intense, confirming successful expression in the supernatant.
