ASPARAGINASE FROM ASPERGILLUS ORYZAE EXPRESSED IN ASPERGILLUS ORYZAE

摘要

At the request of the Codex Committee on Food Additives and Contaminants (Codex Alimentarius Commission, 2006) at its thirty-eighth session, the Committee evaluated an enzyme preparation containing the enzyme asparaginase (l-asparagine amidohydrolase;EC 3.5.1.1), which it had not evaluated previously. Asparaginase hydrolyses the amide in the amino acid l-asparagine to the corresponding acid, resulting in l-aspartate (aspartic acid) and ammonia. Apart from asparagine, asparaginase acts only on glutamine and has no activity on other amino acids. Asparaginase has no activity on asparagine residues in peptides or proteins.
