Nucleic acid molecules coding for a protein with deacetylase activity, said protein, and method for the production of chitosan

Abstract

The invention relates to nucleic acid molecules selected from the group comprising: a) nucleic acid molecules that code for a form of the polypeptide with the derived amino acid sequence according to SEQ ID No. 3, said polypeptide having a deacetylase activity; b) nucleic acid molecules that comprise the nucleotide sequence according to SEQ ID No. 1 or SEQ ID No. 2 and that code for one form of said polypeptide; c) nucleic acid molecules that code for a fragment or a derivative of a polypeptide that is coded by a nucleic acid molecule according to a) or b), wherein one or more amino acid groups are conservatively substituted in said derivative as compared to said polypeptide, and wherein said fragment or derivative has a deacetylase activity; d) nucleic acid molecules that have a sequence identity of at least 95% with a nucleic acid molecule according to a) to c), and that code for a polypeptide with deacetylase activity; e) nucleic acid molecules that have a sequence identity of at least 70% with a nucleic acid molecule according to a) to c) and that code for a polypeptide with deacetylase activity; f) or the complementary string of a nucleic acid molecule according to a) to e).
