Biology Direct, 2012 Background In eukaryotes, the CMG (CDC45, MCM, GINS) complex containing the replicative helicase MCM is a key player in DNA replication. Archaeal homologs of the eukaryotic MCM and GINS proteins have been identified but until recently no homolog of the ...

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.

Recent Insights Into the Structure, Function, and Evolution of the RNA-Splicing Endonucleases
Frontiers in Genetics, 2019 RNA-splicing endonuclease (EndA) cleaves out introns from archaeal and eukaryotic precursor (pre)-tRNA and is essential for tRNA maturation. In archaeal EndA, the molecular mechanisms underlying complex assembly, substrate recognition, and catalysis have

Activity and Regulation of Archaeal DNA Alkyltransferase [PDF]
Journal of Biological Chemistry, 2012 Agents that form methylation adducts in DNA are highly mutagenic and carcinogenic, and organisms have evolved specialized cellular pathways devoted to their repair, including DNA alkyltransferases. These are proteins conserved in eucarya, bacteria and archaea, acting by a unique reaction mechanism, which leads to direct repair of DNA alkylation damage ...

A hot origin of dissimilatory sulfite reduction catalyzed by DsrAB in the Paleoarchean Era
mLife, EarlyView.Abstract Dissimilatory sulfite reduction (DSR) has been essential to microbial energy metabolism in the biogeochemical sulfur cycle since the Paleoarchean Era. However, due to the lack of an integrated assessment of geological record and genomic data, the evolutionary origin of DSR remains elusive in terms of time, habitat, and genetic basis.

Viral Hijack of Filamentous Surface Structures in Archaea and Bacteria
Viruses, 2021 The bacterial and archaeal cell surface is decorated with filamentous surface structures that are used for different functions, such as motility, DNA exchange and biofilm formation. Viruses hijack these structures and use them to ride to the cell surface

PCR performance of a thermostable heterodimeric archaeal DNA polymerase [PDF]
Frontiers in Microbiology, 2014 DNA polymerases are versatile tools used in numerous important molecular biological core technologies like the ubiquitous polymerase chain reaction (PCR), cDNA cloning, genome sequencing, and nucleic acid based diagnostics. Taking into account the multiple DNA amplification techniques in use, different DNA polymerases must be optimized for each type of
