Descrição geral
2-Iminobiotin is a cyclic guanidino analog of biotin that has high affinity for avidin at high pH (>9) and low affinity at low pH (<6). The proteins that are iminobiotinylated are selectively contained within the avidin column at pH 9 to 11 and may be eluted at pH 4 or by the addition of biotin. This technique may be very useful in the study of cell surface proteins by labeling and selectively recovering the components that are periodate-sensitive from intact human erythrocyte surface. 2-Iminobiotin reversibly inhibits NOS (nitric oxide synthases) via its guanidino group. It inhibits NO biosynthesis and may be important to understand the binding-site interactions for this important class of enzymes. NOS oxidizes the guanidino-nitrogen of L-arginine to produce nitric oxide and L-citrulline.
Aplicação
2-Iminobiotin has been used as a competitive inhibitor to bind to biotic binding sites on streptavidin in order to restore fluorescence signal.

Streptavidin binds 2'-iminobiotin in a pH-dependent fashion--affinity decreases as the pH is lowered. This property makes the purification of compounds conjugated to streptavidin or immobiotin possible under mild conditions by affinity chromatography. In order to understand the molecular details of
