Abstract

The opium poppy Papaver somniferum is the source of the narcotic analgesics morphine and codeine. Salutaridine reductase (SalR; EC 1.1.1.248) reduces the C-7 keto group of salutaridine to the C-7 (S)-hydroxyl group of salutaridinol in the biosynthetic pathway that leads to morphine in the opium poppy plant. P. somniferum SalR was overproduced in Escherichia coli and purified using cobalt-affinity and size-exclusion chromatography. Hexagonal crystals belonging to space group P6(4)22 or P6(2)22 were obtained using ammonium sulfate as precipitant and diffracted to a resolution of 1.9 A.

摘要

罂粟(Papaver somniferum)是麻醉性镇痛药吗啡和可待因的来源。在罂粟植物中通向吗啡的生物合成途径中,水杨醛苷还原酶(SalR;EC 1.1.1.248)将水杨醛苷的C-7酮基还原为水杨醛醇的C-7(S)-羟基。罂粟SalR在大肠杆菌中过量表达,并使用钴亲和色谱和尺寸排阻色谱进行纯化。以硫酸铵作为沉淀剂获得了属于空间群P6(4)22或P6(2)22的六方晶体,其衍射分辨率为1.9 Å。
