The protein sequence of an archaeal catalase-peroxidase

Biochimie, 1998
The gene encoding a catalase-peroxidase of archaeal origin, the halophilic catalase-peroxidase from Haloarcula marismortui, was sequenced. The primary structure proposed was confirmed by Edman degradation and mass spectrometry analyses of proteolytic fragments of the purified protein.

Functions of Archaeal Nucleoid Proteins: Archaeal Silencers are Still Missing

2019
It is well known that horizontally transferred genes (HTGs) contribute to the adaptation of archaea to their living environment. Archaea have acquired HTGs not only from other archaea but also from bacteria. HTGs should be integrated into the host archaeal transcriptional networks to become functional.

Sec61β – a component of the archaeal protein secretory system

Trends in Biochemical Sciences, 2002
Sec61p/SecYEG complexes mediate protein translocation across membranes and are present in both eukaryotes and bacteria. Whereas homologues of Sec61alpha/SecY and Sec61gamma/SecE exist in archaea, identification of the third component (Sec61beta or SecG) has remained elusive. Using PSI-BLAST, the archaeal counterpart of Sec61beta has been detected. With

Uncovering the structure-function aspects of an archaeal CsaA protein

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2021
CsaA is known to function as a protein secretion chaperone in bacteria. Homologs of CsaA are also found in archaea while they are absent in eukaryotes. This paper presents the biophysical, biochemical analysis and crystallographic structure determination of CsaA from a thermoacidophilic archaeon Picrophilus torridus (PtCsaA).

Protein–protein interactions in the archaeal core replisome

Biochemical Society Transactions, 2011
Most of the core components of the archaeal chromosomal DNA replication apparatus share significant protein sequence similarity with eukaryotic replication factors, making the Archaea an excellent model system for understanding the biology of chromosome replication in eukaryotes.

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 ...

Archaeal Orc1/Cdc6 Proteins

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
