Riassunto

La 5′-nucleotidasi del plasma seminale bovino é inibita competitivamente da nucleosidi di- e trifosfato. L'inibizione osservata in presenza di ADP o ATP é rimossa da ioni magnesio a concentrazioni fisiologiche. Questo risultato suggerisce che l'attività della 5′-nucleotidasi secreta dalle vescichette seminali sia, al pari di altre presenti in vari organi dei mammiferi, modulata da cationi bivalenti.
