Recombinant production and structural studies of the Aplysia water-borne protein pheromone enticin indicates it has a novel disulfide stabilized fold.


Enticin is one of three Aplysia proteins released during egg laying that act in concert with the pheromone attractin to attract other Aplysia and stimulate mating behavior. Whereas the enticin cDNA predicts a 69-residue mature protein, enticin isolated from the albumen gland was found to be posttranslationally processed in vivo by cleavage at Arg(50… (More)
