Bacteriophage Lambda Receptor Protein in Escherichia Coli K-12: Lowered Affinity of Some Mutant Proteins for Maltose-binding Protein in Vitro
Overview
Affiliations
Mutant and wild-type LamB proteins (phage lambda receptor proteins) were purified by affinity chromatography with immobilized maltose-binding protein, and their transport functions were tested in reconstituted liposomes. Two mutant proteins exhibited a marked decrease in affinity for immobilized maltose-binding protein, as well as altered transport rates.
