L-Phenylephrine (L-PE) is a pharmaceutical compound, synthesized by chemical method and used in anti-allergic drug, cold medicine and vasopressin. Beacause chemical synthesis of L-PE involved multifarious and dangerous processes, the main purpose of this study is to establish a whole cell conversion process to convert 1-(3-hydroxyphenyl)-2-(methylamino)ethanone (HPMAE) to L-PE instead of chemical methods. Aminoketone asymmetric reductase (akr) genes were cloned from 6 strains of Rhodococcus genus. Use E. coli NovaBlue harboring akr gene as a biocatalyst to convert 20 mM HPMAE to D-PE (>99% e.e.) with conversion yield 86.5% and productivity 877.98 mg l-1 h-1 at 45℃ pH 7.0 for 4 h reaction. Using immobilized metal affinity chromatography to recover AKR, in vitro AKR activity assay demonstrated that AKR protein was a NADPH-dependent enzyme, which exhibit a specific activity of 116 mU/mg to 1-amino-2-propanol. Analyze AKR kinetic for the Km, Kcat and Kcat/Km, the value are 49.36 mM, 0.87 min-1 and 17 .63 min-1M-1 respectively.

L-Phenylephrine(L-PE)是化學合成的藥物,廣泛應用在抗過敏藥、感冒藥及血管加壓劑之中。由於目前化學合成生產L-PE牽涉到複雜危險的反應過程,本研究的主要目標在於建立一全細胞轉換(whole cell conversion)產程以取代化學合成中,將L-PE之前驅物1-(3-hydroxyphenyl)-2-(methylamino)ethanone (HPMAE)還原成為L-PE的步驟。以Rhodococcus菌株進行微生物酵素的篩選,利用高效能液相層析儀解析HPMAE及PE,沒有發現產生PE的酵素活性。以基因選殖方式,在6株Rhodococcus之中選殖到aminoketone asymmetric reductase (akr)酵素基因。將E. coli NovaBlue轉型株攜帶akr基因作為生物催化劑(biocatalyst)可以轉換HPMAE產生D-PE。加入20 mM HPMAE 在45℃ pH 7.0中反應4小時可得到17.30 mM D-PE (>99% e.e.),轉換率(conversion yield) 86.5%及生產率(productivity) 877.98 mg l-1 h-1。利用immobilized metal affinity chromatography純化回收AKR酵素蛋白並分析in vitro AKR酵素活性。顯示AKR為對NADPH專一性酵素,催化1-amino-2-propanol的比活性(specific activity)為116 mU/mg,酵素動力學分析結果,Km值為49.36 mM、Kcat值0.87 min-1及Kcat/Km值17.63 min-1M-1。
