Potassium binding protein (Kbp) selectively binds potassium in its active site, inducing a conformation change in the N and C termini regions, respectively. This makes it a distinguishable candidate for in vivo or in vitro potassium monitoring using fluorescence resonance energy transfer (FRET). Coupling this protein with two fluorophores can permit potassium detection. Potassium detection is vital as potassium is used in cells to play an important role in fluid and electrolyte homeostasis, which is crucial for functioning of the neurological, cardiovascular, and immune system. Potassium is also a crucial biomarker used in clinical medicine for tracking the progression and status of patients with hypo- or hyperkalemia, which may provide insights into Chronic Kidney Disease (CKD) or diabetic ketoacidosis. As such a biosensor for potassium tracking may be of great interest to patients and clinicians. This part includes a mutated Kbp to have a cysteine modification that will bind cysteine linker arms and be used for biosensor immobilization allowing the detection of potassium. | Potassium binding protein (Kbp) selectively binds potassium in its active site, inducing a conformation change in the N and C termini regions, respectively.

Potassium binding protein with cysteine modification(s) to bind to a biosensor.
Potassium binding protein (Kbp) selectively binds potassium in its active site, inducing a conformation change in the N and C termini regions, respectively. This makes it a distinguishable candidate for in vivo or in vitro potassium monitoring using fluorescence resonance energy transfer (FRET). Coupling this protein with two fluorophores can permit potassium detection. Potassium detection is vital as potassium is used in cells to play an important role in fluid and electrolyte homeostasis, which is crucial for functioning of the neurological, cardiovascular, and immune system. Potassium is also a crucial biomarker used in clinical medicine for tracking the progression and status of patients with hypo- or hyperkalemia, which may provide insights into Chronic Kidney Disease (CKD) or diabetic ketoacidosis. As such a biosensor for potassium tracking may be of great interest to patients and clinicians. This part includes a mutated Kbp to have a cysteine modification that will bind cysteine linker arms and be used for biosensor immobilization allowing the detection of potassium.
