Abstract
Official abstract text for this publication.
Disclosed is an Escherichia coli producing 2-deoxy-scyllo-inosose (DOI), which, from a sucrose non-PTS gene group, has at least a sucrose hydrolase (CscA)-encoding gene and which is provided with a DOI production system or has an enhanced DOI production system. The Escherichia coli preferably further includes a system to enhance sugar uptake capacity. There is also disclosed a method of producing DOI from a plant-derived raw material containing sucrose by using the Escherichia coli.
First claim
Opening claim text (preview).
The invention claimed is: 1. A 2-deoxy-scyllo-inosose (DOI)-producing Escherichia coli , which is provided with a DOI production system or has an enhanced DOI production system by introducing a DOI synthase (BtrC)-encoding gene derived from Bacillus circulans into a host, wherein a phosphoglucose isomerase (Pgi)-encoding gene and a glucose-6-phosphate-1-dehydrogenase (Zwf)-encoding gene of the host are disrupted, and only a sucrose hydrolase (CscA)-encoding gene derived from E…
