General description
Lipases hydrolyze ester bonds of triacylglycerols and in some conditions, catalyze the synthesis of ester bonds by transesterification. Lipase from Rhizopus niveus exists as a single polypeptide chain with a molecular mass of about 30-34kDa.
Application
Lipase from Rhizopus niveus has been used to determine the positional distribution of fatty acids within triacylglycerol by hydrolysis of the acyl ester linkage at C-1 and C-3. It has also been used to induce intragastric lipolysis and study its effects on felodipine (a medication) release from a hydrophilic, extended release tablet.
Biochem/physiol Actions
Lipase from Rhizopus niveus is specifically used to produce cocoa butter substitutes.
トリグリセリド、ジグリセリド、モノグリセリドが加水分解されます(反応速度の高い順)。
Other Notes
基質特異性:1-位と3-位を優先的に加水分解します(中鎖~長鎖脂肪酸)。至適pH:5.0~7.0。至適温度:30~45°C。保護官能基の選択的な酵素的除去(C末端COOH基)。
1 Uは、pH 7.7、40°C、1分間で、1 μmolの脂肪酸をトリグリセリドから遊離させる酵素量に相当します(オリーブ油を基質として使用)。この300ユニットは、トリオレイン(製品番号62314)をpH 8.0、40°Cで基質として使用した場合の約1 Uに相当します。
Note: When triacetin is used as substrate, the pH is 7.4. Incubation time: 60 minutes.
