Abstrakt: In this review we explore the advantages deriving from the use of either enzymes or sugar binding proteins isolated from thermophilic organisms to develop stable fluorescence biosensors. We report on a novel approach to address the consumption of the analyte by enzyme-based biosensors, namely the utilization of apo-enzymes as non-active forms of proteins which are still able to bind the ligand but cannot transform it into product. We also report recent studies in which the fluorescence labeling of a naturally thermostable binding protein allows a quantitative determination of glucose. [ABSTRACT FROM AUTHOR]
