According to the domain organization, the GGDEF-EAL containing proteins (pfam database, version 17.0) were classified into A and B types. Six hundreds and five of the 621 proteins were in A type, which was also found in the ancient bacteria Aquifex aeolicus VF5 suggesting that this is the ancestor of the GGDEF-EAL proteins. Phylogenetic analysis of GGDEF- and EAL- containing proteins in the genome of V. vulnificus YJ016 revealed that GGDEF-EAL proteins were clustered. Comparative analysis of domain organization of the clads in the EAL tree allowed identification of several duplication events. The results indicated that most of the GGDEF- and EAL- containing proteins arised by gene duplication.
根据pfam资料库(Version 17.0),我们整理同时拥有GGDEF和EAL功能性区域的蛋白质,这些蛋白质可以被区分成两种型态,在总数621个GGDEF-EAL中有高达606个是A型态,而且它在古老的细菌Aquifex aeolicus VF5的基因体中也能找到,因此我们推测它可能是GGDEF-EAL的袓先,藉由分析创伤弧菌中所包含之GGDEF和EAL的演化关系,大部份的GGDEF-EAL会群聚在树型相近的位置,进一步比较在EAL树型上有邻近关系的蛋白质序列,根据他们的长度、与所包含的功能区域,我们找到了一些重制的演化痕迹,这样的结果指出,目前看到大多数的GGDEF 和EAL可能都是经过重制产生。
