Enzymatic transphosphorylation of sugar substrates

摘要

The present invention relates to methods of producing sugar phosphates by enzymatic transphosphorylation, wherein the phosphoryl transfer from phosphate donor substrates to sugar substrates is catalyzed by an enzyme having alpha-glucose-1-phophatase activity. Furthermore, the present invention relates to a biocatalyst having sucrose phosphorylase as well as alpha-glucose-1-phosphatase activity and its use. The production of an enzyme having alpha-glucose-1-phophatase activity and its use in the transphosphorylation of sugar substrates is also presented herein.
