| Outline of Final Research Achievements |
The expression of genes encoding the enzymes required for glycerol metabolism of the lactic acid bacterium Enterococcus faecalis is induced by glycerol or glycerol and oxygen; however, the genes involved in the regulation of glycerol metabolism are yet to be identified.
In the present study, we performed in vitro transposon mutagenesis of E. faecalis and identified several genes required for aerobic glycerol metabolism. Experiments using these transposon mutants indicated that the supply of ribose synthesized via gluconeogenesis is essential for nucleic acid biosynthesis in aerobic glycerol metabolism of E. faecalis.
