Bacterial community composition and functional potential change subtly across gradients in
the surface ocean. In contrast, while there are significant phylogenetic divergences between …

Cyanobacteria are model organisms for photosynthesis and are attractive for biotechnology
applications. To aid investigation of genotype-phenotype relationships in cyanobacteria, we …

Bacteria must balance the different needs for substrate assimilation, growth functions, and
resilience in order to thrive in their environment. Of all cellular macromolecules, the bacterial …

Biological fixation of atmospheric CO 2 via the Calvin–Benson–Bassham cycle has massive
ecological impact and offers potential for industrial exploitation, either by improving carbon …

Caspases accomplish initiation and execution of apoptosis, a programmed cell death
process specific to metazoans. The existence of prokaryotic caspase homologs, termed …

Introducing biosynthetic pathways into an organism is both reliant on and challenged by
endogenous biochemistry. Here we compared the expansion potential of the metabolic network …

Marine and brackish surface waters are highly dynamic habitats that undergo repeated
seasonal variations in microbial community composition and function throughout time. While …

The chemolithotroph Cupriavidus necator H16 is known as a natural producer of the
bioplastic-polymer PHB, as well as for its metabolic versatility to utilize different substrates, including …

Metacaspases are distant homologs of metazoan caspase proteases, implicated in stress
response, and programmed cell death (PCD) in bacteria and phytoplankton. While the few …

Knowledge of the genetic basis for autotrophic metabolism is valuable since it relates to both
the emergence of life and to the metabolic engineering challenge of incorporating CO 2 as …
