而bennett ( 1977 )發現的類囊體膜蛋白可逆磷酸化已成為近年研究的熱點之一,蛋白質連上或是移去磷酸基團都將強烈影響蛋白質的生理活性和性質,這需要類囊體膜蛋白激酶和磷酸酯酶的參與。Both the frequency and intensity of 1146. 0cm - 1 change largely, etc. discussed and compared the mechanism of these interaction in detail we got some conclusions as following : both zn2 + and cd2 + ions can chelate with po2 - and come into being - po2 - me2 + n7 ( purine ) chelate. as to zn2 + ions, when r2. 0, the quantity of po2 - zn2 + n7 is directly linear with r. when r2. 0, zn2 + ions even can chelate with c at n3 - o2 sites and this chelation will disrupt the h - bond between gc base pairs and make the dna structure unstable. as to cd2 + ions, only when r is within 1. 0 - 1. 5 can this chelation take place and the relation of the quantity of this chelate with r is not easy to conclude
通過對這些變化進行詳細討論和分析,我們得到了如下的結論: zn ~ ( 2 + )和cd ~ ( 2 + )都可以跟dna的磷酸基團螯合,形成- po _ 2 ~ - … me ~ ( 2 + ) … n7 ( g )螯合物,但是前者的螯合跟離子濃度有很大的關系,在摩爾濃度比小於2 . 0時,螯合物的生成量跟r成正比關系,而後者的螯合跟離子的關系不是很明顯,只有當r處於1 . 0至1 . 5之間時,螯合作用才能進行,並且螯合物的生成量跟r之間沒有很明顯的關系存在。In bacterial, many enzymes compete for intracellular pep, especially the phosphotransferase system which is responsible for glucose transport in e. coli. this system uses pep as a phosphate donor and converts it to pyruvate, which is less likely to recycle back to pep

人組蛋白h3是堿性核蛋白,富含精氨酸,在生理條件下, h3的精氨酸帶正電荷,而dna的磷酸基團帶負電荷,所以組蛋白和dna分子主要依靠靜電引力相結合。A mechanism that interprets this phenomenon was proposed as follows : the adsorbents can interact with phospholipid of ldl through calcium ion cross - linking of the phospholipid phosphate groups of ldl and the carboxyl groups of sde ligands. on the other hand, the electrostatic interaction between the positive charge of the phospholipid choline nitrogen of ldl and the negative charge of carboxyl groups of sde ligands is enhanced by the calcium cross - linking of the phosphate groups of neighboring phospholipids in ldl
其可能的原因是:在吸附體系中如存在大量的cay ,一方面ca可以作為橋梁連接ldl所含磷脂極性頭部的磷酸基團和吸附微珠配體上的孩基;另一方面又可交聯相鄰磷脂間的磷酸基團,從而促進ldl所含磷脂極性頭部的膽堿n 」與配體竣基的相互作用。Dinucleotide a compound of two nucleotides linked by their phosphate groups. important examples are the coenzymes nad and fad
