Enzyme Function FUNCTION: Protein with lectin and protease activity involved in the establishment of trypanosome infections in tsetse flies. Binds D-glucosamine and agglutinates bloodstream-form trypanosomes and rabbit red blood cells. Capable of inducing transformation of bloodstream-form trypanosomes into procyclic (midgut) forms in vitro. {ECO:0000269|PubMed:16619615}.
