Description
Cellulose Acetate Esterase is an enzyme that de-acetylates cellulose acetate by hydrolyzing the acetyl ester moieties in cellulose acetate. The gene sequence is obtained from a bacterium, Neisseria Sicca that uses cellulose acetate as its sole source of carbon. Purified Cellulose Acetate Esterase has a high activity on Cellulose Acetate, but it has been shown to have activity on p-nitrophenyl acetate and some other p-nitrophenyl esters.

Since industrially made cellulose acetate is a plastic that tends to take a long time to biodegrade in the environment, the use of this enzyme could help in rapid degradation of cellulose acetate by removing the acetate groups. This part could be used specifically for de-acetylating cellulose acetate and other related esters.
Notes
Neisseria Sicca secretes the enzyme extracellularly and hence it has a signal sequence to aid for secretion. In order to use the gene in E.coli, we removed the signal sequence of Neisseria Sicca and added an E.coli specific secretion tag. In addition to that, we added a his-tag at the c'terminus end of the protein to aid purification of the protein.
