A light-driven sodium ion pump in marine bacteria.
TLDR
It is discovered that the marine flavobacterium Krokinobacter eikastus possesses two rhodopsins, the first, KR1, being a prototypical proton pump, while the second, KR2, pumps sodium ions outward. Expand
Diversity and functional analysis of proteorhodopsin in marine Flavobacteria.
TLDR
It is revealed that PR-mediated proton transport can create the sufficient membrane potential for the ATP synthesis in native flavobacterial cells. Expand
Structural basis for Na+ transport mechanism by a light-driven Na+ pump
TLDR
Crystal structures of KR2 under neutral and acidic conditions are presented, which represent the resting and M-like intermediate states, respectively, and reveal the molecular basis for light-driven non-proton cation pumps and provide a framework that may advance the development of next-generation optogenetics. Expand
Functional characterization of flavobacteria rhodopsins reveals a unique class of light-driven chloride pump in bacteria
TLDR
The genome of the marine flavobacterium Nonlabens marinus S1-08T encodes three different types of rhodopsins, and functional analysis demonstrated that NM-R1 andNM-R2 are light-driven outward-translocating H+ and Na+ pumps, respectively, representing the first chloride-pumping r Rhodopsin uncovered in a marine bacterium.

Multilocus Sequence Typing and Phylogenetic Analyses of Pseudomonas aeruginosa Isolates from the Ocean
TLDR
The intraspecies phylogenetic relationship between marine strains and other strains from various geographical locations is clarified and it can be concluded that the ocean P. aeruginosa strains have diverged from other isolates and form a distinct cluster based on MLST and phylogenetic analyses of seven housekeeping genes. Expand
Rubricoccus marinus gen. nov., sp. nov., of the family 'Rhodothermaceae', isolated from seawater.
TLDR
A coccoid- and amorphous-shaped, non-gliding, reddish bacterium, designated SG-29(T), was isolated from seawater in the western North Pacific Ocean near Japan and classified in a novel genus and species within the family 'Rhodothermaceae', for which the name Rubricoccus marinus gen. nov., sp. Expand
Vibrio azureus sp. nov., a luminous marine bacterium isolated from seawater.
TLDR
It can be concluded that two luminous marine bacterial strains isolated from seawater at Kuroshio Region and Sagami Bay in Japan belong to the same genospecies and represent a novel species of the genus Vibrio, for which the name VIBrio azureus sp. Expand
Photobacterium aquimaris sp. nov., a luminous marine bacterium isolated from seawater.
TLDR
Two luminous marine bacteria isolated from seawater at Sagami Bay in Japan represent a novel species, for which the name Photobacterium aquimaris sp. Expand
A distinct lineage of giant viruses brings a rhodopsin photosystem to unicellular marine predators
TLDR
It is demonstrated that the rhodopsin shared by ChoanoViruses and PgV binds retinal and pumps protons when illuminated, indicating that light-dependent energy transfer systems are likely common components of giant viruses of photosynthetic and phagotrophic marine eukaryotes. Expand
Nonlabens marina sp. nov., a novel member of the Flavobacteriaceae isolated from the Pacific Ocean
TLDR
It was concluded that strains S 1-05 and S1-08T represent a novel species within the genus Nonlabens, for which the name nonlabens marina sp. Expand
