Description
I. セリンエンドペプチダーゼは常にペプチド結合を分解する加水分解酵素である;
II. この活性は、酵素の一次構造に関連して、互いに遠く離れているが、活性な触媒中心(「触媒トリアド(catalytic triad)」)における高次構造により近接しており、それらのアミノ酸残基の一つは常にセリン残基である一群のアミノ酸残基に依存している;
III. CまたはN末端からポリペプチドを分解し、そしてそれらの特異性に応じて、トリペプチド、ジペプチドまたは代わりに個々のアミノ酸を遊離する「エキソペプチダーゼ」とは対照的に、セリンエンドペプチダーゼは、タンパク質またはポリペプチドの内部に位置するペプチド結合を分解する;
IV. セリンエンドペプチダーゼは非可逆的にフッ化フェニルメチルスルホニル(PMSF)によって阻害を受け、これはPMSFが活性中心のセリン残基をスルホニル化するからである;
V. セリンエンドペプチダーゼは非可逆的にジイソプロピルフルオロホスフェート(DFP)によって阻害を受け、これはDFPが活性中心のセリン残基をリン酸化するからである。
上記の特徴を有するセリンエンドペプチダーゼは、酵素クラスE.C. 3.4.21にまとめられる。各ケースにおけるこのクラスの個々のメンバーは一つの追加番号を含んでいる。セリンエンドペプチダーゼE.C. 3.4.21の酵素クラスの現在知られているメンバーを表1に列記する。

図1
図1は、+52℃で48時間インキュベートしたF Xa液体調製物における種々の濃度での酢酸アンモニウムの安定化効果を図示したものである。検体中に含まれるF Xa活性を、発色性F Xa基質の卵割により、t=0時間、1時間、6時間、24時間および48時間で測定した。t=0時間で測定した活性を100%に等しいと設定した。後の時点で測定した活性はこれと比較した。F Xa液体調製物中の酢酸アンモニウムの存在下でF Xaの熱安定性が酢酸アンモニウムを含まないコントロールに比較して増大していることが明らかに理解できる。安定性の増加は濃度依存的であり、すなわち酢酸アンモニウム濃度が高くなれば安定性効果も増大する。
図2は、+52℃で48時間インキュベートしたF Xa液体調製物における種々の濃度でのポリアミノ酸ポリグリタメートおよびポリアスパルテートの安定化効果を図示したものである。検体中に含まれるF Xa活性を、t=0時間、1時間、6時間、24時間および48時間で測定した。t=0時間で測定した活性を100%に等しいと設定した。後の時点で測定した活性はこれと比較した。F Xa液体調製物中のポリアミノ酸の存在下でF Xaの熱安定性がポリアミノ酸を含まないコントロールに比較して増大していることが明らかに理解できる。安定性の増加は濃度依存的であり、すなわちポリアミノ酸濃度が高くなれば安定性効果も増大する。
図3は比較実験を記載しそして+52℃で48時間インキュベートしたF Xa液体調製物における種々の濃度でのアミノ酸リシンの不安定化効果を図示したものである。F Xa液体調製物中のL−リシンの存在下でF Xaの熱安定性がL−リシンを含まないコントロールに比較して減少していることが明らかに理解できる。安定性の減少は濃度依存的であり、すなわちL−リシン濃度が高くなれば不安定化効果も増大する。本発明の安定化物質に対して、F Xa液体調製物にL−リシンを添加することは安定化作用を持たないだけではなく、反対の作用、すなわちF Xaの不安定化さえもたらす。
図4は、+52℃で48時間インキュベートしたトロンビン液体調製物における種々の濃度での酢酸アンモニウムの安定化効果を図示したものである。検体中に含まれるトロンビン活性を、t=0時間、1時間、6時間、24時間および48時間で測定した。t=0時間で測定した活性を100%に等しいと設定した。後の時点で測定した活性はこれと比較した。トロンビン液体調製物中の酢酸アンモニウムの存在下でトロンビンの熱安定性が酢酸アンモニウムを含まないコントロールに比較して増大していることが明らかに理解できる。安定性の増加は濃度依存的であり、すなわち酢酸アンモニウム濃度が高くなれば安定性効果も増大する。
酢酸アンモニウム、ポリアミノ酸またはグリセロールおよびアミノ酸の添加による本発明のF Xa液体調製物の製造、ならびにそれらのストレス条件下での熱安定性
ヒトF Xを得るために、ヒト血漿から得られたプロトロンビン複合体凍結乾燥物を溶解
し、そして25% (w/v)硫酸アンモニウムを加えてプロトロンビン複合体調製物のタンパク質を沈殿させた。沈殿したタンパク質混合物を遠心分離により上清から分離し、再懸濁し、そしてクエン酸三ナトリウム塩二水和物緩衝液(4.0g/l)、pH 6.5に対して透析した。透析された液を続いてデキストラン硫酸−セファロース材上でのクロマトグラフィーに付した。F Xは、クエン酸三ナトリウム塩二水和物緩衝液(pH 6.5)中で塩化ナトリウムの勾配により、プロトロンビン複合体の残余のタンパク質成分から分離した。F Xを含む画分を合わせて、6g/Lのトリスヒドロキシメチルアミノメタンおよび0.6g/Lの塩化カルシウム二水和物を含む緩衝液(pH 8.0)の10倍体積に対して透析した。F XからF Xaへの活性化は、Xa因子のプールの1LあたりRVV(ラッセルヘビ毒)を5mg加えて行い、続いて室温で終夜インキュベーションした。このようにして得られたF Xaを硫酸アンモニウム沈殿法により濃縮し、そして30g/Lのトリスヒドロキシメチルアミノメタン、60g/Lの塩化ナトリウム(pH 8.0)中に回収した。保存のために、F Xaを含むタンパク質溶液を続いて凍結乾燥した。凍結乾燥物はF Xaを1mgあたり2U含み、この1U単位は1mLの正常血漿中に含まれている酵素の量に相当する。
L−リシンの添加によるF Xa液体調製物の製造およびそれのストレス条件下での熱安定性(比較実験)
実施例1の実験と同様に、F Xa調製物を異なった濃度のアミノ酸L−リシンを含有する緩衝液1を用いて作成した比較実験を、実施した。L−リシンの不安定化作用を図3および付随する図の説明で示した。
酢酸アンモニウムの添加による本発明のトロンビン液体調製物の製造
商業的に入手できるトロンビン凍結乾燥物を用いた。これは、ヘパリン、マンニトール、NaClおよびアプロチニンを加えた凍結乾燥ウシトロンビンであった。この凍結乾燥物を、緩衝液2(トリスを12g/L、NaClを9g/L、pH 8.2)中、またはさらに種々の濃度で酢酸アンモニウムを含有する緩衝液2中で溶解した。こうして得られたトロンビン調製物は1mLあたり約4〜5IUのトロンビンを含んでいる。
