The major tropism determinant (Mtd, 40 kDa), the receptor-binding protein of Bordetella bacteriophage, varies greatly in sequence. Variation in Mtd depends on a phage-encoded retroelement that belongs to a family of retroelements implicated in generating sequence diversity in various phage and bacterial genomes. The second domain forms a beta sandwich structure.	Domain

This is the N-terminal domain of major tropism determinant (Mtd), a retroelement-encoded receptor-binding protein. Mtd-N forms a three-fold symmetric beta-prism. This resembles the pseudo three-fold-symmetric beta-prisms of monocot lectins, but lacks residues in these lectins identified as binding carbohydrates. The beta-prism and beta-sandwich domains reinforce overall trimeric assembly and therefore may have indirect roles in stabilizing the backbone of the variable region [1].	Domain
