Expression, purification and structural analysis of recombinant rBdh-2His₆, a spermadhesin from buck (Capra hircus) seminal plasma.

Spermadhesins, a family of secretory proteins from the male genital tract of ungulate species, belong to the group of animal lectins. Spermadhesins have a prominent role in different aspects of fertilisation, such as spermatozoid capacitation, acrosomal stabilisation, sperm-oviduct interaction and during sperm-oocyte fusion. Proteins (spermadhesins) in buck seminal plasma were described.
