Stable 6-phosphogluconolactonase, method of its production and its use.

摘要

The invention relates to a 6-phosphogluconolactonase which, after approximately 20 hours at pH 7.0 and 20 DEG C, has an enzyme activity of at least 90% of the initial activity. Also described is a method for producing the enzyme from Leuconostoc. The enzyme is preferentially suitable for determining ATP or reactants which can be converted into 6-phosphogluconolactone.
