中文摘要：

在一个染色体，蛋白质的集合被领域总科的复制和联合形成。P 环包含核苷酸 triphosphate (NTP ) 水疗院放射激光总科大规模在 archaea 之中被复制并且让最不同的搭挡总科，细菌 andeukarya。这里，我们学习复制的分布和在 169 个完成的染色体包含 NTPhydrolases 总科的 p 环的联合。当在一个染色体的领域的全部的数字更大时，复制和联合包含 NT 的 p 环合伙“ P 水疗院放射激光是更多。Thisphenomenon 在后生动物是更明显的。丰富的分布和搭挡的联合联系到蛋白质的功能。因为后生动物的复杂性，在后生动物的那些分布与在另外的王国的那些很不同。最后，在包含 NTP 水疗院的 p 环的复制和联合之间的关系放射激光在不同染色体的总科被描述。它适合一条幂定律。

英文摘要：

In a genome the set of proteins are formed by duplication and combination of domain superfamilies. P-loop containing nucleotide triphosphate （NTP） hydrolases superfamily is massively duplicated and has the most different partner superfamilies among archaea, bacteria and eukarya, Here, we study the distributions of duplication and combination of p-loop containing NTP hydrolases superfamily in 169 completed genomes. When the total number of domains in a genome is larger, duplication and combination partners of p-loop conraining NTP hydrolases are more. This phenomenon is more obvious in metazoa. The distributions of abundance and corn bination of partners relate to the functions of the protein. Those distributions in metazoa are very different from those in other kingdoms because of complexity of metazoa. Finally the relationship between duplication and combination of p-loop containing NTP hydrolases superfamily in different genomes is described. It fits a power law.
