Like PTL I, this lectin binds preferentially to N-acetylgalactosamine,
with this sugar also being the most inhibitory monosaccharide.
However, in contrast to PTL I, this lectin prefers the
β anomeric configuration. PTL II shows a high affinity toward
blood group H structures and the T-antigen. PTL I and PTL II
also differ in their erythrocyte agglutinating properties.
Inhibiting Sugar: 100 mM N-acetylgalactosamine
