<i>Corynebacteria </i>strain having enhanced 5′-xanthosine monophosphate productivity and a method of producing 5′-xanthosine monophosphate using the same

摘要

Disclosed is a novel microorganism which has a malate dehydrogenase activity higher than that of a wild-type. Also, a recombinant vector which has the structure shown in the cleavage map of FIG. 1, a Corynebacteria strain transformed therewith, and a method of producing 5′-xanthosine monophosphate by culturing the transformed strain are disclosed.

主权项

1. An isolated Corynebacteria ammoniagenes strain, which strain has a malate:quinone oxidoreductase activity higher than that of a wild-type Corynebacteria ammoniagenes, wherein the higher MQO activity is achieved by increasing the number of mqo gene copies encoding the malate dehydrogenase, or replacing or modifying a promoter of an mqo gene, wherein said mqo gene is the Corynebacteria ammoniagenes mqo gene.
