陽イオン交換樹脂であるスルホン化キトパール(富士紡績社製)600gを充填したカラム(直径5cm×高さ30cm)を脱イオン水で十分に洗浄した後、このカラムに未殺菌脱脂乳360L(pH6.7)を流速25ml/minで通液した。通液後、カラムを脱イオン水で十分洗浄し、2.0Mの塩化ナトリウムを含む0.02M炭酸緩衝液(pH7.0)で溶出した。そしてラクトパーオキシダーゼを含有する溶出画分をS-SepharoseFFカラム(アマシャムバイオサイエンス社製)に吸着させ、脱イオン水で十分洗浄し、10mMのリン酸緩衝液(pH7.0)で平衡化した後、0~2.0Mの塩化ナトリウムのリニアグラジエントで吸着した画分を溶出し、ラクトパーオキシダーゼを含む画分を回収した。そしてその画分をHiLoad 16/60 Superdex75pg(アマシャムバイオサイエンス社製)を用いたゲル濾過クロマトグラフィーで処理した。この溶出液を逆浸透膜により脱塩した後、凍結乾燥してラクトパーオキシダーゼの純度が90%のラクトパーオキシダーゼ画分27gを得た。これら一連の処理を25回繰り返した。
発酵乳類に含まれるアンジオジェニンやアンジオジェニン分解物ならびにラクトパーオキシダーゼやラクトパーオキシダーゼ分解物の測定は、特開2008-164511号公報の方法を改変して実施した。即ち、超純水5mlに発酵乳類86μlを加え、これに1/1,000量のギ酸を添加し、試料溶液とした。この溶液10μlをドライアップした後、8M尿素および1mMトリス(カルボキシエチル)フォスフィン(TCEP)を含む0.1M重炭酸アンモニウム20μlに溶解し、56℃で30分間加温した。室温に戻した後、100mMヨードアセトアミド溶液5μlを添加して、遮光下で30分反応させた。これに、54μlの超純水を添加後、0.1μg/mlトリプシン10μlおよび0.1μg/mlリシルエンドペプチダーゼ10μlを添加して、37℃で16時間反応させた。その後、3μlのギ酸を添加して、反応を停止し、測定試料用ペプチド溶液とした。各試料溶液を10fmol/μlの内部標準ペプチド溶液(含0.1%ギ酸、0.02%トリフルオロ酢酸(TFA)、2%アセトニトリル)で6倍に希釈し、希釈した溶液2.5μlをLC/MS/MSにて分析を行った。
ラクトパーオキシダーゼの測定対象イオンは、ペアレントイオンがNH2-IHGFDLAAINLQR-COOHでm/z 734.4、MS/MSターゲットイオンがNH2-IHGFDLA-COOHでm/z 754.4、アンジオジェニンの測定対象イオンは、ペアレントイオンがNH2-YIHFLTQHYDAK-COOHでm/z 768.8、MS/MSターゲットイオンがNH2-FLTQHYDAK-COOHでm/z 1122.8で測定した。内部標準ペプチドは、ペアレントイオンがNH2-ETTVFENLPEK-COOH(但し、Pの炭素はC13、窒素はN15で標識)でm/z 656.9であり、MS/MSのターゲットイオンは、NH2-FENLPEK-COOH(但し、Pの炭素はC13、窒素はN15で標識)でm/z 882.4で行った。
MSにはLCQ Advantageを用いた。得られたクロマトグラムから各タンパク質のピーク面積を求め、内部標準ペプチドとの比から濃度を求めた。
100℃にて10分間加熱殺菌した10%の還元脱脂粉乳にスターターカルチャーを添加したもの100gに参考例2のアンジオジェニン画分8mgと参考例3のラクトパーオキシダーゼ画分22mgを混合し、常法に従って発酵させて、発酵乳類(比較例品1)を得た。得られた発酵乳類には、アンジオジェニン及び/又はアンジオジェニン分解物が0.9mg/100g含まれており、アンジオジェニン及び/又はアンジオジェニン分解物に対するラクトパーオキシダーゼ及び/又はラクトパーオキシダーゼ分解物の質量比は27であった。
