查询词典 molecule

The structure of the compound 〓(1) consists of a pentanuclear molecule which is center-symmetric. One W atom is coordinated by four S atoms and two Cu atom. As expected, the Fe atoms are sandwiched between two staggered pentadiene rings. The most interesting aspect of the structure is that Fe-C-P-Cu-P-Cconstitutes a distorted hexagon and Fe-Cu-W-Cu-Fe is nearly in a line.

结构是以W原子为对称中心含有五个金属原子的线型结构，W原子与四个μ〓-S和两个Cu原子配位；Fe原子在两个戊二烯环中间形成一个三明治夹心结构；Fe〓-C〓-P〓-Cu〓-P〓-C〓-构成扭曲的六边形，由于两边1，1'-双二茂铁配体的作用导致Cu-S键的拉长。

Erve growth factor can combine with its" receptor (one of tyrosine protein kinase receptor coded by proto - oncogene tyrosine kinase, TrkA), Causing the molecule of receptors to gather on the cell surface, and the tyrosine protein in cytoplasmic domain may be activated, three tyrosine base in the kinase domain of its" receptor and two tyrosine base at other domain be phosphated, thus, phosphated tyrosine receptor kinase became the bracket which absorb all kinds of connective proteins and kinases.

GF与其酪氨酸受体激酶受体(由原癌基因trk编码的一种酪氨酸蛋白激酶受体，TrkA)相结合，引起受体分子在细胞表面发生二聚体化，然后受体细胞内结构上酪氨酸活性被激活，使受体自身结构中位于激酶结构域的三个酪氨酸残基及在此结构域外的两个酪氨酸残基发生自身磷酸化，这样，磷酸化的酪氨酸受体激酶A便成为吸收各种连接蛋白质和酶的支架。
