(a)ポリ(3-ヒドロキシプロピオネート)開始剤を生合成する段階;および
(b)段階(a)で製造されたポリ(3-ヒドロキシプロピオネート)開始剤の存在下に、ラクチド単量体を開環重合してポリラクチド-ポリ(3-ヒドロキシプロピオネート)ブロック共重合体を製造する段階。
[化学式1]
MA1 pA2 2-p
実施例1~4
(1)ポリ(3-ヒドロキシプロピオネート)オリゴマーの生合成
1)高分子量のポリ(3-ヒドロキシプロピオネート)の生産
本発明による高分子量のポリ(3-ヒドロキシプロピオネート)の生合成のために、まず発酵基質として3-ヒドロキシプロピオネートを含む発酵液を製造するために次の条件により発酵を行った。具体的には、発酵のための菌株としてGDHおよびALDH酵素遺伝子を有するE.coli W3110を使用した。培地としてはM9を使用し、グリセロール70g/Lを基質として使用して発酵させて3-ヒドロキシプロピオネートを生産した。
低分子量のポリ(3-ヒドロキシプロピオネート)を生産するために、韓国特許第10-2017-0028186号公報に開示された方法により(本文献は参考文献として本発明の範囲に含まれる)、プロピオニル-CoAトランスフェラーゼ遺伝子(pct)としてクロストリジウムプロピオニカム(Clostridium propionicum)由来のプロピオニル-CoAトランスフェラーゼ(CP-PCT)の変異体、PHA合成酵素遺伝子としてシュードモナス属MBEL 6-19(KCTC 11027BP)由来のPHA合成酵素の変異体およびベクターとしてpBluescript II (Stratagene Co.,USA)を使用して、pPs619C1310-CPPCT540組換えベクターを製造して、これを用いてpPs619C1249.18H-CPPCT540ベクターを製造した後、これをldhAがノックアウト(knock-out)されたE.coli XL1-BlueΔldhAに電気穿孔法(electroporation)を用いて形質転換させて、組換えE.coli XL1-BlueΔldhAを製作した。
前記1)で製造された20,000g/molの重量平均分子量を有する高分子量のポリ(ヒドロキシプロピオネート)を蒸溜水に入れ、塩酸を用いてpH2に合わせて酸触媒の条件下で加水分解を行った。加水分解を速かに行うために100℃オーブンにて前記ポリ(ヒドロキシプロピオネート)サンプルをそれぞれ24時間、および72時間の間加水分解させて、重量平均分子量がそれぞれ2100および21800(g/mol)のポリ(3-ヒドロキシプロピオネート)オリゴマーを収得した。
500mLの丸いフラスコにL-ラクチド16g、前記(1)で製造された多様な重量平均分子量を有するポリ(3-ヒドロキシプロピオネート)オリゴマーおよびスズ(II)2-エチルヘキサノエート0.04g(0.1mol%;Sigma Aldrich社)を下記表1に記載された含有量で投入して十分に真空をかけて常温で4時間の間真空乾燥した。
500mLの丸いフラスコにL-ラクチド、ドデカノールおよびスズ(II)2-エチルヘキサノエートを下記表2に記載された含有量で投入して十分に真空をかけて常温で4時間の間真空乾燥した。
1.NMR(Nuclear Magnetic Resonance)分析
NMR分析は三重共鳴5mm探針(probe)を有するVarian Unity Inova(500MHz)分光計を含むNMR分光計を使用して常温で行った。NMR測定用溶媒(CDCl3)に分析対象物質として実施例1~4でそれぞれ製造されたブロック共重合体および重合体を約10mg/ml程度の濃度に希薄して使用し、化学シフトはppmで表した。
実施例1~4のブロック共重合体および比較例1および2の重合体を、ゲル透過クロマトグラフィー(GPC)(Waters:Waters707)にかけることにより、重量平均分子量(Mw)および数平均分子量(Mn)をそれぞれ求めた。測定するブロック共重合体/重合体を4000ppmの濃度になるようにテトラヒドロフランに溶解させて、GPCに100μlを注入した。GPCの移動相にはテトラヒドロフランを使用し、1.0mL/分の流速で流入させ、分析は35℃で行った。カラムはWaters HR-05、1、2、4E の4個を直列に連結した。検出器としてはRI and PAD Detecterを用いて35℃で測定した。その結果を表4に示した。
