Archaeal viruses, especially viruses that infect hyperthermophilic archaea of the phylum Crenarchaeota, constitute one of the least understood parts of the virosphere. However, owing to recent substantial research efforts by several groups, archaeal viruses are starting to gradually reveal their secrets. In the present review, we summarize the current knowledge ...

The recent advances in membrane protein crystallography have provided extremely valuable structural information of the superfamily of GPCRs (G-protein-coupled receptors). This has been particularly true for a few receptors whose structure was solved several times under different biochemical conditions. It follows that the mechanisms of receptor conformational equilibrium and related ...

Cells release extracellular vesicles in response to external factors or in a physiological way. Microvesicles and exosomes originate in cells in different ways and, depending on their contents, may have multiple biological effects on other cells and the environment. The host cell-parasite relationship could be changed dramatically by the plasticity ...

Biofilms or multicellular structures become accepted as the dominant microbial lifestyle in Nature, but in the past they were only studied extensively in bacteria. Investigations on archaeal monospecies cultures have shown that many archaeal species are able to adhere on biotic and abiotic surfaces and form complex biofilm structures. Biofilm-forming ...

Most integral membrane proteins of yeast with two or more membrane-spanning sequences have not yet been crystallized and for many of them the side on which the active sites or ligand-binding domains reside is unknown. Also, bioinformatic topology predictions are not yet fully reliable. However, so-called low-resolution biochemical methods can ...

Receptor coupling to different G-proteins and β-arrestins has been described for a number of GPCRs (G-protein-coupled receptors), suggesting a multi-state model of receptor activation in which each receptor can assume a number of different active conformations, each capable of promoting the coupling to a specific effector. Consistently, functional-selective ligands and ...

Every living cell is covered with a dense and complex array of covalently attached sugars or sugar chains. The majority of these glycans are linked to proteins via the so-called glycosylation process. Protein glycosylation is found in all three domains of life: Eukarya, Bacteria and Archaea. However, on the basis ...

Class B GPCRs (G-protein-coupled receptors) share heptahelical topology and G-protein binding with other superfamily members, yet have unique structures and modes of activation. Natural ligands for these receptors are moderate-length peptides with C-terminal α-helices. NMR and crystal structures of the peptide-bound disulfide-bonded receptor N-terminal domains demonstrate that these helices occupy ...
