MANNOSE-BINDING PROTEIN-A MUTANT (QPDWGHV) COMPLEXED WITH N-ACETYL-D-GALACTOSAMINE
OverviewOverview
The mammalian hepatic asialoglycoprotein receptor, a member of the C-type, animal lectin family, displays preferential binding to, N-acetylgalactosamine compared with galactose. The structural basis for, selective binding to N-acetylgalactosamine has been investigated. Regions, of the carbohydrate-recognition domain of the receptor believed to be, important in preferential binding to N-acetylgalactosamine have been, inserted into the homologous carbohydrate-recognition domain of a, mannose-binding protein mutant that was previously altered to bind, galactose. Introduction of a single histidine residue corresponding to, residue 256 of the hepatic asialoglycoprotein receptor was found to cause, a 14-fold increase in the relative affinity for N-acetylgalactosamine, compared with galactose. ...
