Title:
NOVEL MICROORGANISM, MALTOSE PHOSPHORYLASE, TREHALOSE PHOSPHORYLASE, AND PROCESSES FOR PRODUCING THESE
Document Type and Number:
WIPO Patent Application WO/2005/003343
Kind Code:
A1
Abstract:
A novel microorganism belonging to the genus Paenibacillus which has the ability to produce a maltose phosphorylase and a trehalose phosphorylase; a novel maltose phosphorylase which acts only on maltose to cause the &agr -1,4-glucopyranoside bond in the maltose to reversively undergo phosphorolysis; a novel trehalose phosphorylase which acts only on trehalose to cause the &agr -1,4-glucopyranoside bond in the trehalose to reversively undergo phosphorolysis; and processes for producing these enzymes. The enzymes are more easily obtained than in conventional processes. A considerable reduction in incubation time can also be attained. The enzymes have high stability to temperatures and have almost the same optimum-pH range.
