About Lectin Frontier DataBase (LfDB)


Significance of LfDB

Lectin Frontier DataBase (LfDB) provides quantitative interaction data in terms of the affinity constants (Ka) of a series of lectins toward a panel of pyridylaminated (PA) glycans obtained by an automated frontal affinity chromatography with fluorescence detection (FAC-FD) system (Fig. 1). Since the data are accurate and reliable, providing the absolute values of sugar-protein interactions, LfDB would be a valuable resource in the studies of glycan-related biology.


Present status of LfDB

LfDB consists of the Lectin Information Page to provide the basic information on lectins and the Interaction Page to provide the interaction data obtained by the FAC-FD system. Interaction data are shown in a bar graph format by either an actual measurement (V-V0) or an association constant (Ka). LfDB also provides a "1-parameter" function that helps to find a key structural element among the related glycan structures.


Future perspectives

LfDB will be updated to provide more information on the glycan-binding properties of lectins identified from various organisms. Data of other glycan-binding proteins, such as anti-glycan antibodies, will also be included in the future.
