DNA microarray analysis of central carbohydrate metabolism:: Glycolytic/gluconeogenic carbon switch in the hyperthermophilic crenarchaeum Thermoproteus tenax

In order to unravel the role of regulation on transcript level in central carbohydrate metabolism (CCM) of Thermoproteus tenax, a focused DNA microarray was constructed by using 85 open reading frames involved in CCM. A transcriptional analysis comparing heterotrophic growth on glucose versus autotrophic growth on CO2-H-2 was performed.
