cex coding sequence encoding Cellulomonas fimi exoglucanase

The cellulolytic bacterium Cellulomonas fimi uses an exoglucanase (from cex, accession M15824) along with 3 endoglucanases in the degradation of cellulose into cellobiose, before use B-glucosidase to catalyse the conversion of cellobiose to D-glucose.

Characterization from iGEM18-UESTC-China

Molecular weight

This gene codes for a protein of 485 amino acids with a molecular mass of 51.2 kDa.

Enzyme digestion

Enzyme activity

We constructed a plasmid containing cenA gene BBa_K118023, cex gene BBa_K118022. We transformed this plasmid into BL21(DE3).

We used an intracellular fraction (crude enzyme solution) obtained by ultrasonication to carry out an experiment for measuring total enzyme activities by the method of filter paper assay.
