monomeric protein 中文意思是什麼
-
The purified enzyme was a monomeric protein whose optimum ph was 8. 0. inhibitor study demonstrated that it was a metalloprotease and contained sulfhydryl groups essential for catalytic activity. its activity was inhibited by divalent cations such as zn2 +, mn2 +, and the kj values of zn2 +, mn2 + were imm
這種酶溫度適應范圍較廣，在較大溫度變化區間內都具有明顯的活性，但是對緩沖溶液ph值的變化卻很敏感，體外以明膠為底物時最適溫度為38oc ，最適ph值為8 -
It was found that prophenoloxidase ( propo ), isolated as a monomeric protein, had a molecular weight of 87. 5 kda, and a 77 kda phenoloxidase molecule was often contained in preparations. the 87. 5 kda propo had a very low enzymatic activity on 0. 02 mol / l l - dopa, whereas the 77 kda po had a very high enzymatic activity on it
實驗發現，酚氧化酶原（ prophenoloxidase ）的分子量為87 . 5kda左右，在實驗操作過程中極易發生降解或自身降解，變成有活性的大小約77kda的酚氧化酶， 1 sds可使該酶原全部被激活而成為有活性的酚氧化酶。 -
Gfral is an extracellular protein that is attached to the outer cell membrane by gpi - anchor and could not transducted signalling directly. according to the original model, a gdnf dimer first binds to either monomeric or dimeric gfral, and the gdnf - gfral complex then interacts with two ret molecules, thereby inducing their homodimerization and tyrosine autophosphorylation
傳統觀點認為： gdnf首先與gfr 1結合形成gdnf - gfr 1復合物，此復合物再與ret結合形成三聚體復合物，引起ret的二聚化，並引起酪氨酸殘基自磷酸化，從而引起下游的信號轉導。
