Archaeal orc1/cdc6 proteins.

Sub-cellular biochemistry, 2012
The initiation of DNA replication in most archaeal genomes is mediated by proteins related to eukaryotic Orc1 and Cdc6. Archaeal replication origins have been mapped and their interactions with Orc1/Cdc6 proteins have been characterized at the biochemical level. Structural and biophysical studies have revealed the basic rules of sequence recognition by

The archaeal PCNA proteins.

Biochemical Society Transactions, 2011
PCNA (proliferating-cell nuclear antigen) is a ring-shaped protein that encircles duplex DNA and plays an essential role in many DNA metabolic processes. The PCNA protein interacts with a large number of cellular factors and modulates their enzymatic activities.

Overexpression of archaeal proteins in Escherichia coli

Biotechnology Letters, 1998
Six archaeal proteins containing a high number of Escherichia coli rare codons in their genes were not well expressed in E. coli. These genes showed a five to twenty-fold increase in production when expressed in the presence of a plasmid harboring and expressing the argU and ileX genes encoding rare tRNAs (tRNA arg(de)AGA/AGG and tRNA ile(de)AUA ...

Proteomic characterization of archaeal ribosomes reveals the presence of novel archaeal-specific ribosomal proteins.

Journal of Molecular Biology, 2011
Protein synthesis occurs in macromolecular particles called ribosomes. All ribosomes are composed of RNA and proteins. While the protein composition of bacterial and eukaryotic ribosomes has been well-characterized, a systematic analysis of archaeal ribosomes has been lacking.
