Embden-Meyerhof-Parnas and Entner-Doudoroff pathways in Thermoproteus tenax: metabolic parallelism or specific adaptation?

Zeitschriftenaufsatz / Fach: Biologie
Genome data as well as biochemical studies have indicated that - as a peculiarity within hyperthermophilic Archaea - Thermoproteus tenax uses three different pathways for glucose metabolism, a variant of the reversible EMP (Embden-Meyerhof-Parnas) pathway and two different modifications of the ED (Entner-Doudoroff) pathway, a non-phosphorylative and a semi-phosphorylative version. An overview of the three different pathways is presented and the physiological function of the variants is discussed.
