The LysR family of transcriptional regulators represents the most abundant type of
transcriptional regulator in the prokaryotic kingdom. Members of this family have a …

Prokaryotes constitute a single kingdom, Bacteria, here divided into two new subkingdoms:
Negibacteria, with a cell envelope of two distinct genetic membranes, and Unibacteria …

Marine and terrestrial photosynthetic and chemoautotrophic microorganisms assimilate
considerable amounts of carbon dioxide. Like green plastids, the predominant means by …

▪ Abstract The last decade has seen significant advances in our understanding of the
physiology, ecology, and molecular biology of chemoautotrophic bacteria. Many ecosystems …

The nutritional versatility of facultative autotrophs requires efficient overall control of their
metabolism. Most of these organisms are Proteobacteria that assimilate CO 2 via the highly …

The phylogenetic diversity of the ribulose-1, 5-bisphosphate carboxylase/oxygenase
(RuBisCO, EC 4.1. 1.39) large-subunit genes of deep-sea microorganisms was analyzed …

I attempt to sketch a unified picture of the origin of living organisms in their genetic,
bioenergetic, and structural aspects. Only selection at a higher level than for individual …

Abstract BACKGROUND: Cyanobacterium Synechocystis sp. PCC 6803 has been used
widely as a model system for the study of photosynthetic organisms and higher plants. The …

For the metabolically diverse nonsulfur purple phototrophic bacteria, maintaining redox
homeostasis requires balancing the activities of energy supplying and energy-utilizing …

Background Acidithiobacillus ferrooxidans is chemolithoautotrophic γ-proteobacterium that
thrives at extremely low pH (pH 1-2). Although a substantial amount of information is …
