Legium Lectins are widely used as a model system for protein- protein, protein-carbohydrate
interactions. So two legium seeds were elected, as Lens cinarius and Phaselius aureus Roux for
detection of their lectins .Such lectins were extracted, separated and partially characterized as LCL and
PAL. respectively. Two prokaryotic cellular systems Klebsiella pneumoniae and Escherichia coli and
two eukaryotic cellular systems the human erythrocytes as well as the avian T-lymphocyte, were
elected.
Cell typability were studied on K.pneumoniae, E.coli and human erythrocytes , while T-cell
mitogenicity were checked by lectin skin test in avian wing system. Two typing patterns were observed
in both K. pneumoniae and E.coli. togther with LCL untypable isolates of K. pneumoniae and E.coli .
Pantypability was identified in human erythrocyte in both of LCL and PAL. Positive mitogenic
responses were noted in the avian wing test. Thus, both LCL and PAL have typing and mitogenic
potentials. Which could be due protein- protein or protein-carbohydrate interactions.
