It has been suggested that magnesium form a chelated structure with the phosphate groups . 有人指出,鎂與磷酸基因能構成螯合結構。
Dinucleotide a compound of two nucleotides linked by their phosphate groups . important examples are the coenzymes nad and fad 二核苷酸:由磷酸基團連接的兩個核苷酸組成的化合物。例如輔酶nad和fad 。
For example , hexokinase catalyzes the transfer of a high - energy terminal phosphate group form atp to glucose to give glucose 6 - phosphate and adp 例如:己糖激酶可以催化atp最末端的一個高能磷酸鍵轉移到葡萄糖分子上,形成葡萄糖- 6 -磷酸和adp 。
Adp ( adensine diphosphate ) a nucleotide consisting of adenine and ribose with two phosphate groups attached . the second phosphate is attached to the first by a high - energy bond 腺(嘌呤核)苷二磷酸:一種由腺嘌呤和核糖再加上兩個磷酸組成的核苷酸。其中第二個磷酸以高能鍵與第一個磷酸結合。
Chloroplast phosphoprotein were first found in thylakoid membranes by bennett o the attachment or removal of a phosphate group from a protein may have profound effects on that protein ' s activities and properties , the reversible phospharylation of the membrane protein in thykaloid is a dymanic equilibrium process 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。
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。
Arginine rich human histone h3 is a kind of basic nucleosome protein . in the medium of physiological condition , by electrostatic interaction , histone h3 which arginine impart to it a positive charge binds to dna which phosphate groups impart to it a negative charge . in this paper , in order to establish a new technology of transfection , the functional domains la and ii gene segments of pea were lined with histone h3 gene segment , then a recombinant fusion protein was constructed which serves as c arrier for transfer of dna via receptor - mediated endocytosis 本實驗在已成功獲得的pea功能區a ,功能區基因片段與人組蛋白h3基因片段的克隆菌株的基礎上,構建原核表達載體,將克隆質粒pmd - 18t - pea經nco , mlu雙酶切,回收酶切產物;將克隆質粒pmd - 18t - h3經mlu , xho雙酶切,回收酶切產物。
