N-acetyl-α-D-galactosamine deacetylase_Flavonifractor plautii
This encodes a N-acetyl-α-D-galactosamine deacetylase from Flavonifractor plautii originating from the human gut microbiota.
This enzyme removes the acetyl moiety of N-acetyl-α-D-galactosamine (A antigen). This however does not results in full degradation of A antigen a α-D-galactosamine residue remains.
The expression of this enzyme led to significant proteotoxicity shown by an impaired growth of Escherichia coli BL21 (DE3). We thus recommended to use Escherichia coli Rosetta (DE3) pLysS which helps stabilizing pET recombinants encoding proteins.
