CC   -!- FUNCTION: L-rhamnose binding lectin. Has hemagglutinating activity
CC       towards rabbit erythrocytes and human type B erythrocytes.
CC       Hemagglutinating activity is inhibited by smooth-type
CC       lipopolysaccharide (LPS) from S.flexneri 1A and E.coli K12, but not by
CC       rough-type LPS from S.flexneri, E.coli K12 and E.coli EH100.
CC       Agglutinates E.coli K12 and B.subtilis. {ECO:0000269|Ref.1}.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Temperature dependence:
CC         Loses half of its hemagglutinating activity after heating at 50
CC         degrees Celsius for 120 minutes. Activity is abolished by heating at
CC         80 degrees Celsius for 60 minutes. {ECO:0000269|Ref.1};
