Fucosyltransferase substrate specificity and the order of fucosylation in invertebrates.

abstract：:Sulfated O-linked oligosaccharides from the sea urchin egg receptor have been shown to bind to acrosome-reacted sperm and to inhibit fertilization in a competitive bioassay. However, the inhibitory activity of these isolated chains was much lower than that of a recombinant protein representing a portion of the extrace...
