Frequent mutations within the genomic magnetosome island of Magnetospirillum gryphiswaldense are mediated by RecA.

Journal of bacteriology - 1 Oct 2011

Kolinko Isabel, Jogler Christian, Katzmann Emanuel, Schüler Dirk

Abstract excerpt

Genes for magnetosome formation in magnetotactic bacteria are clustered in large genomic magnetosome islands (MAI). Spontaneous deletions and rearrangements were frequently observed within these regions upon metabolic stress. This instability was speculated to be due to RecA-dependent homologous recombination between the numerous sequence repeats present within the MAI. Here we show that a RecA-deficient strain...
