Abstract
The invention is directed to a lectin derived carbohydrate binding-peptide which inhibits cell-mediated immune responses and has the amino acid sequence SPYGRC. The peptide binds terminally linked .alpha.-sialic acid (2.fwdarw.3).beta.Gal- and .alpha.-sialic (2.fwdarw.6).beta.Gal-structures and is a acid fragment of the S2 subunit of pertussis toxin produced by Bordetella pertussis.
