Target size of the 5'-nucleotidase in six different smooth muscles was determined by radiation inactivation. The enzyme in the soluble fraction of rat myometrium and vas deferens gave a target size of approximately 80,000 daltons. The plasma membrane bound 5'-nucleotidase however, gave target size of 80,000 to 110,000 daltons in rat gastric fundus and vas deferens and dog stomach and ileum, 135,000 daltons in rat mesenteric artery and 210,000 daltons in rat myometrium.
通过辐射失活法测定了六种不同平滑肌中5'-核苷酸酶的靶标大小。大鼠子宫肌层和输精管可溶性部分中的该酶靶标大小约为80,000道尔顿。然而，质膜结合的5'-核苷酸酶在大鼠胃底和输精管、犬胃和回肠中的靶标大小为80,000至110,000道尔顿，在大鼠肠系膜动脉中为135,000道尔顿，在大鼠子宫肌层中为210,000道尔顿。
