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. Aspects include a biosensor for the determination of a presence or concentration of glucose, comprising a glucose-binding protein and a reporter group attached to the glucose-binding protein. Binding of glucose to a glucose-binding domain of the glucose-binding protein causes a change in signaling by the reporter group.

- Thus, the biosensors do not require refrigeration or a cold chain for distribution, permitting a wider range of applicability such as in-the-field use and reducing the cost of the sensor product.
- In non-limiting examples, a ligand-binding protein has no deletions or insertions compared to a naturally occurring protein e.
- Mutations include but are not limited to substitutions, insertions, and deletions.
- The self-calibrating nature of a ratiometric measurement removes the necessity for carrying out on-board calibration tests prior to each measurement.
