| Outline of Final Research Achievements |
Hyperthermophilic archaeon Thermococcus kodakarensis evolves hydrogen on starch or pyruvate which is associated with oxidative degradation of the growth substrates to acetyl-CoA, and acetate was formed from acetyl-CoA as an end product. T. kodakarensis is thought to lack TCA cycle because genes for enzymes converting C6 carboxylic acids are missing in the genome, whereas some related hyperthermophilic archaea possess the enzymes although the function in carbon/energy metabolisms has been unclear.
In this study, the genes of the missing TCA cycle enzymes, derived from the related hyperthermophile, were introduced into T. kodakarensis, and investigated the effects of the TCA cycle enzymes on the growth of and metabolisms in T. kodakarensis.
