Aphanothece halophytica is a halotolerant alkaliphilic cyanobacterium which can grow in media of up to 3.0 M NaCl and pH 11. This cyanobacterium can synthesize betaine from glycine by three-step methylation using S-adenosylmethionine as a methyl donor. To unveil the mechanism of betaine uptake and efflux in this alkaliphile, we isolated and characterized a(More)
γ-Aminobutyric acid (GABA) is known as an inhibitory neurotransmitter in human, while in plants, GABA is an intermediate for amino acid metabolism and also is accumulated in response to a wide range of environmental stress. In the present study, GABA accumulation in Aphanothece halophytica was increased 2-fold in mid-log phase cells grown under salt stress(More)
