Phylogenetic diversity of the carbon monoxide-utilizing prokaryotes and their divergent carbon monoxide metabolisms in the human gut microbiome

Y. A. Katayama, R. Kamikawa, T. Yoshida

The paper identifies over a thousand CO-utilizing prokaryotes in the human gut microbiome, revealing diverse CO metabolism and a degenerated Wood-Ljungdahl pathway.

Encyclopaedia of family A DNA polymerases localized in organelles: Contribution of genes from bacteria including the proto-mitochondrion.

R. Harada, Y. Hirakawa, A. Yabuki, E. Kim, E. Yazaki, R. Kamikawa, K. Nakano, M. Elias, Y. Inagaki

This study identifies and classifies 134 family A DNA polymerase sequences from diverse eukaryotes, revealing their evolutionary origins and suggesting the last eukaryotic common ancestor had two mitochondrial DNAPs.

Taxonomic difference in marine bloom-forming phytoplanktonic species affects dynamics of both bloom-responding prokaryotes and prokaryotic viruses

H. Takebe, K. Tominaga, T. Isozaki, T. Watanabe, K. Yamamoto, R. Kamikawa, T. Yoshida

This study shows that different phytoplankton species affect the dynamics of prokaryotes and their viruses during blooms.

Proton-pumping rhodopsins in marine diatoms

S. Yoshizawa, T. Azuma, K. Kojima, K. Inomura, M. Hasegawa, Y. Nishimura, M. Kikuchi, G. Armin, H. Miyashita, K. Ifuku, T. Yamano, A. Marchetti, H. Fukuzawa, Y. Sudo, R. Kamikawa

This study identifies diatom rhodopsin as a light-driven proton pump localized to plastid membranes and suggests it contributes to a CO2-concentrating mechanism in diatoms.
