Abstract

Four non-magnetic mutants of Magnetospirillum gryphiswaldense strain MSR-1 were isolated by transposon mutagenesis and found to contain interruption of either the mamO or mamE gene within the mamAB operon. Studies indicated that mamO and mamE genes are essential for magnetosome crystal biomineralization in MSR-1. This is the first report of a single gene (mamO or mamE) whose mutation affects crystal biomineralization in MSR-1.

摘要

通过转座子诱变，从 Magnetospirillum gryphiswaldense 菌株 MSR-1 中分离出了四个非磁性突变体，发现它们的 mamAB 操纵子中的 mamO 或 mamE 基因中断。研究表明，mamO 和 mamE 基因对于 MSR-1 中的磁小体晶体生物矿化是必需的。这是第一个报道单个基因（mamO 或 mamE）突变影响 MSR-1 中晶体生物矿化的报告。
