The present subject matter provides glucose biosensors as well as compositions, devices, and methods comprising such biosensors. Provisional Application No. The present invention relates to compositions and methods for detecting and determining the concentration of glucose. Most current glucose-monitoring technologies rely on enzymes for which glucose is one of the substrates. Glucose concentration measurements are therefore subject to variations in second substrate concentrations consumed in the enzyme reaction, such as oxygen in the case of glucose oxidase. Additional complications arise in systems where reaction rates are measured for enzymes immobilized on electrodes. Improved ratiometric fluorescent glucose sensors are needed. The compositions and methods described herein provide a solution to these and other disadvantages associated with earlier glucose sensors. Provided herein are semisynthetic, reagentless, ratiometric fluorescent glucose biosensors based on the hyperthermophilic ttGBP1 and homologues thereof. These engineered compounds include biosensors that respond to glucose concentrations in clinically relevant concentration ranges.
