Genetic analysis of the role of the ABC transporter Ota and Otb in glycine betaine transport in Methanosarcina mazei Gö1.

Archives of microbiology - 1 Apr 2009

Saum Regina, Mingote Ana, Santos Helena, Müller Volker

Abstract excerpt

The methanogenic archaeon Methanosarcina mazei Gö1 accumulates glycine betaine in response to hypersalinity but differs from most other methanoarchaea in having two gene clusters both encoding a potential glycine betaine transporter, Ota and Otb. We have created mutants with either ota or otb deleted to address their role in salt adaptation. The mutants were not impaired in growth at low or high salt, neither at...
