Abstract

The gene encoding FtZ was cloned from triangular disc-shaped extremely halophilic archaeon Haloarcula japonica strain TR-1. Nucleotide sequencing analysis of the possible ftsZ gene revealed that the structural gene consisted of an open reading frame of 1,182 nucleotides encoding 394 amino acids. The deduced amino acid sequence of the Ha. japonica FtsZ showed high identities with those Halobacterium salinarom, Haloferax volcanii and Haloferax mediterranei FtsZs.

摘要

从三角形盘状极端嗜盐古菌日本嗜盐碱杆菌TR-1菌株中克隆了编码FtsZ的基因。对可能的ftsZ基因进行核苷酸测序分析表明，该结构基因由一个1182个核苷酸的开放阅读框组成，编码394个氨基酸。日本嗜盐碱杆菌FtsZ推导的氨基酸序列与盐沼盐杆菌、嗜盐栖热菌和地中海嗜盐栖热菌的FtsZ具有高度同源性。
