我们系统地对大肠杆菌K-12中的所有非必需基因进行了一系列精确定义的单基因缺失。开放阅读框编码区用侧翼为FLP识别靶位点的卡那霉素盒替换,通过使用一步法失活染色体基因和设计用于在切除抗性盒后产生框内缺失的引物。在4288个靶基因中,获得了3985个突变体。为了缓解高通量研究中遇到的问题,为每个缺失的基因保存两个独立的突变体。这些突变体-"Keio收集“-不仅为未知基因功能和基因调控网络的系统分析提供了新的资源,而且还为常见菌株背景下突变效应的全基因组测试提供了新的资源。coli K-12 BW 25113。我们无法破坏303个基因,包括37个功能未知的基因,这些基因是必需基因的候选基因。通过GenoBase(http://ecoli.aist-nara.ac.jp/)进行分发。
We have systematically made a set of precisely defined, single-gene deletions of all nonessential genes in Escherichia coli K-12. Open-reading frame coding regions were replaced with a kanamycin cassette flanked by FLP recognition target sites by using a one-step method for inactivation of chromosomal genes and primers designed to create in-frame deletions upon excision of the resistance cassette. Of 4288 genes targeted, mutants were obtained for 3985. To alleviate problems encountered in high-throughput studies, two independent mutants were saved for every deleted gene. These mutants—the ‘Keio collection'—provide a new resource not only for systematic analyses of unknown gene functions and gene regulatory networks but also for genome-wide testing of mutational effects in a common strain background, E. coli K-12 BW25113. We were unable to disrupt 303 genes, including 37 of unknown function, which are candidates for essential genes. Distribution is being handled via GenoBase (http://ecoli.aist-nara.ac.jp/).
