Examination of a soluble fraction derived from homogenates of rabbit kidney papilla revealed the existence of a 15-hydroxyprostaglandin dehydrogenase specific for A-type prostaglandins. Prostaglandins of the E- and F-series were not substrates for this enzyme. In agreement with published data, the 15-hydroxyprostaglandin dehydrogenase(s) derived from the kidney cortex were found to degrade all prostaglandins examined (PGE, PGF, PGA) in the presence of added cofactor NAD. Thus it is evident that in this species the kidney 15-hydroxyprostaglandin dehydrogenases are anatomically compartmentalized so that the papilla is able to metabpable of degrading E-, F-, and A-type prostaglandins by this metabolic pathway.
对兔肾乳头匀浆的可溶性部分进行检测,发现存在一种对A型前列腺素具有特异性的15-羟基前列腺素脱氢酶。E系列和F系列前列腺素不是该酶的底物。与已发表的数据一致,发现从肾皮质提取的15-羟基前列腺素脱氢酶在添加辅因子NAD的情况下能够降解所有检测的前列腺素(PGE、PGF、PGA)。因此很明显,在该物种中,肾脏的15-羟基前列腺素脱氢酶在解剖学上是分隔的,以至于乳头能够通过这种代谢途径代谢降解E型、F型和A型前列腺素。
