(57) [Summary] [Structure] Stable for storage at low temperature and frozen Method for producing pyruvate orthophosphate dikinase using a novel pyruvate orthophosphate dikinase having extremely stable properties such as melting and also belonging to the genus Microbispora and having pyruvate orthophosphate dikinase-producing ability Is. [Effect] Compared to conventional pyruvate orthophosphate dikinase, this enzyme is extremely stable against storage in the low temperature range and freeze / thaw. When used for the measurement of MP, pyrophosphate, calcium, magnesium, ammonium, etc., these can be measured accurately. |
