A novel scenario for the evolution of haem-copper oxygen reductases.
TLDR
It is proposed that the Archaea domain acquired terminal oxidases by gene transfer from the Gram-positive bacteria, implying that these enzymes were not present in the last common ancestor before the divergence between Archaea and Bacteria.About:

THE EARLY HISTORY OF ATMOSPHERIC OXYGEN: Homage to Robert M. Garrels
TL;DR: In this paper, a review of the Precambrian history of atmospheric oxygen is presented, starting with a brief discussion of the possible nature and magnitude of life before the evolution of oxygenic photosynthesis, followed by a summary of the various lines of evidence constraining oxygen levels through time.

TL;DR: Comparison genomic analyses indicate functionally significant lateral gene-transfer events between the genus Nitrospira and anaerobic ammonium-oxidizing planctomycetes, which share highly similar forms of NXR and other proteins reflecting that two key processes of the nitrogen cycle are evolutionarily connected.

The CLUSTAL_X windows interface: flexible strategies for multiple sequence alignment aided by quality analysis tools.
TL;DR: ClUSTAL X is a new windows interface for the widely-used progressive multiple sequence alignment program CLUSTAL W, providing an integrated system for performing multiple sequence and profile alignments and analysing the results.

Cell biology and molecular basis of denitrification.
TL;DR: Denitrification is intimately related to fundamental cellular processes that include primary and secondary transport, protein translocation, cytochrome c biogenesis, anaerobic gene regulation, metalloprotein assembly, and the biosynthesis of the cofactors molybdopterin and heme D1.
Journal ArticleDOI
The Grotthuss mechanism
TL;DR: In this paper, it is suggested that the molecular mechanism behind prototropic mobility involves a periodic series of isomerizations between H 9 O 4 + and H 5 O 2 +, the first trigerred by hyrdogen-bond cleavage of a second-shell water molecule and the second by the reverse, hydrogen-bonder formation process.

TL;DR: Two possible proton pathways for pumping, each spanning from the matrix to the cytosolic surfaces, were identified, including hydrogen bonds, internal cavities likely to contain water molecules, and structures that could form hydrogen bonds with small possible conformational change of amino acid side chains.
