Description
ホスホリラーゼを上記の目的に使用するためには酵素調製物の純度をある程度高めることが望ましく、このような酵素調製物を得るためにはホスホリラーゼ生産菌を培養した後、菌体(細胞)回収、菌体洗浄、菌体破砕、酵素画分回収、精製等の複雑な工程が必要となる(例えば、特許文献1〜5参照)。またこの際、菌体破砕のために溶菌酵素やキレート剤などを添加する必要があるのに加えて菌体成分のほとんどが溶出するため、ホスホリラーゼ純度を上げるための精製工程の負荷が大きくなるのを避けることができない。
尚、斯かるホスホリラーゼ生産菌は、天然又はUV照射や化学変異剤例えばN-methyl-N'-nitro-N-nitrosoguanidine(MNNG)やethylmethane sulfonate(EMS)(C. Guhrie & G. R. Fink, Methods in Enzymology vol. 194, pp273-281 Academic Press Inc.)等の処理を施すことによって、ホスホリラーゼ産生能が向上した変異株であってもよい。
Corynebacterium vitaeruminis JCM1323、Corynebacterium callunae IFO15359、Corynebacterium glutamicum JCM1321及びCorynebacterium glutamicum JCM1321をMNNG処理することにより得られたホスホリラーゼ高生産変異株Corynebacterium glutamicum KSM-MP669(FERM AP-20036)を、SCD寒天培地(日本製薬株式会社)に塗末し30℃にて培養した。本菌の一白金耳を液体培地(0.67%のYeast Nitrogen Base(Difco社)、50, 100,200 mMのリン酸緩衝液(pH7)、15%のデキストリン(sigma社 potato由来))に接種し、30℃で6日間振とう培養を行った。遠心分離により菌体を除去した培養液上清のマルトデキストリンホスホリラーゼ活性を測定した。
Claims (1)
- リン酸類又はその塩の濃度が400mM〜1.2Mである培地中でロイコノストック属細菌を培養し、培地中に生成されたホスホリラーゼを採取することを特徴とするホスホリラーゼの製造法。
