Protein-protein interactions leading to recruitment of the host DNA sliding clamp by the hyperthermophilic Sulfolobus islandicus rod- shaped virus 2 [PDF]
Viruses infecting hyperthermophilic archaea typically do not encode DNA polymerases, raising questions regarding their genome replication. Here, using a yeast two-hybrid approach, we have assessed interactions between proteins of Sulfolobus islandicus ...

Protein acetylation in archaea, bacteria, and eukaryotes [PDF]
Proteins can be acetylated at the alpha-amino group of the N-terminal amino acid (methionine or the penultimate amino acid after methionine removal) or at the epsilon-amino group of internal lysines.

An archaeal homolog of proteasome assembly factor functions as a proteasome activator. [PDF]
Assembly of the eukaryotic 20S proteasome is an ordered process involving several proteins operating as proteasome assembly factors including PAC1-PAC2 but archaeal 20S proteasome subunits can spontaneously assemble into an active cylindrical ...

DNA-Interacting Characteristics of the Archaeal Rudiviral Protein SIRV2_Gp1 [PDF]
Whereas the infection cycles of many bacterial and eukaryotic viruses have been characterized in detail, those of archaeal viruses remain largely unexplored. Recently, studies on a few model archaeal viruses such as SIRV2 (Sulfolobus islandicus rod-shaped virus) have revealed an unusual lysis mechanism that involves the formation of pyramidal egress ...

Investigation of the transcriptional response of Sulfolobus solfataricus to damaging agents [PDF]
It is vital for the survival of an organism that it can repair damage to its DNA. Exogenous and endogenous sources of damage are dealt with by a variety of repair pathways that have evolved to repair specific types of damage. Organisms in the archaeal

Identification of Archaea-specific chemotaxis proteins which interact with the flagellar apparatus
Background Archaea share with bacteria the ability to bias their movement towards more favorable locations, a process known as taxis. Two molecular systems drive this process: the motility apparatus and the chemotaxis signal transduction system.

Protein-Protein Interaction Changes in an Archaeal Light-Signal Transduction [PDF]
Negative phototaxis inNatronomonas pharaonisis initiated by transient interaction changes between photoreceptor and transducer.pharaonisphoborhodopsin (ppR; also calledpharaonissensory rhodopsin II,psR-II) and the cognate transducer protein,pHtrII, form a tight 2 : 2 complex in the unphotolyzed state, and the interaction is somehow altered during the ...

Functional genomic and advanced genetic studies reveal novel insights into the metabolism, regulation, and biology of Haloferax volcanii [PDF]
The genome sequence of Haloferax volcanii is available and several comparative genomic in silico studies were performed that yielded novel insight for example into protein export, RNA modifications, small non-coding RNAs, and ubiquitin-like Small ...

Ribosomal protein L7Ae is a subunit of archaeal RNase P [PDF]
To the mounting evidence of nonribosomal functions for ribosomal proteins, we now add L7Ae as a subunit of archaeal RNase P, a ribonucleoprotein (RNP) that catalyzes 5′-maturation of precursor tRNAs (pre-tRNAs). We first demonstrate that L7Ae coelutes with partially purified Methanococcus maripaludis
