Isolation and characterization of a novel antistress gene from Chlamydomonas sp W80

Here we report the isolation and characterization of the Chlamydomonas sp. W80-derived Go ATP synthase subunit II WCFII homologue gene. Intracellular ATP concentration and stress-tolerance of Escherichia coli were increased by transformation with WCFII. We propose that WCFII-mediated stress tolerance is due to enhanced accumulation of intracellular ATP. (C) 2009, The Society for Biotechnology, Japan. All rights reserved.
