集胞藻6803中丝氨酸/苏氨酸激酶系统发育和功能概述
Phylogenic and Functional Profile of Ser/Thr Kinases in Synechocystis sp.PCC 6803
摘要
Abstract
Signal perception and transduction for organisms are tightly associated with their adaptability to environments.For signal transduction systems,two-component kinase systems or Ser/Thr kinase systems both in eukaryotes and prokaryotes have been studied and reviewed.As a prokaryotic photosynthetic model organism,except for the typical two-component His-Rep kinase systems,Synechocystis sp.PCC 6803 also possesses 12 genes encoding putative eukaryotic Ser/Thr kinases,which can be divided into 2 subfamilies according to their structural features,PKN2 subfamily and ABC1 subfamily.Genes encoding Ser/Thr kinases belonging to the PKN2 subfamily have been investigated mostly,while the rest belonging to the ABC1 subfamily mostly are functionally unknown.In this paper,the prediction of conserved domains and motifs,as well as protein cellular localizations of these 12 Ser/Thr kinases in Synechocystis sp.PCC 6803 was investigated.As the representative monocotyledon and dicotyledon,rice and Arabidopsis were chosen as reference objects,and by sequence analysis together with 15 rice ABC1Ks and 17 Arabidopsis ABC1Ks,the potential functions and evolutionary relationship of Ser/Thr kinases in Synechocystis sp.PCC 6803 were discussed,which would provide new insights into a more comprehensive understanding of Ser/Thr kinase signaling process in Synechocystis sp.PCC 6803.关键词
