BULL SEMINAL PLASMA PDC-109 FIBRONECTIN TYPE II MODULE
Overview
Bovine seminal plasma PDC-109 binds to sperm surface choline lipids and, promotes sperm capacitation by stimulating the efflux of cholesterol and, phospholipids. The structure of PDC-109 with bound phosphorylcholine was, solved using MAD data of a single platinum site. Its two globular (40 x 50, x 20 A(3)) Fn2 domains are linked and clustered by a short polypeptide., The choline binding sites lie at the same face of the molecule., Phosphorylcholine binds to the Fn2 domains through a cation-pi interaction, between the quaternary ammonium group and a core tryptophan, plus hydrogen, bonding between hydroxyls of exposed tyrosines and the phosphate group., The structure of the PDC-109-oPC complex provides a structural ground for, the sperm membrane-coating mechanism underlying PDC-109-induced, capacitation.
