We study the escape process of nascent proteins at the ribosomal exit tunnel of bacterial Escherichia coli by using molecular dynamics simulations with coarse-grained and atomistic models. It is shown that the effects of hydrophobic and electrostatic interactions on the protein escape at the E. coli’s tunnel are qualitatively similar to those obtained previously at the exit tunnel of archaeal Haloarcula marismortui, despite significant differences in the structures and interactions of the ribosome tunnels from the two organisms.

Estimating the phylogenetic position of bacterial and archaeal organisms by genetic sequence comparisons is considered as the gold-standard in taxonomy. This is also a way to identify the species of origin of the sequence.

The signature amidase from the extremophile archeumSulfolobus solfatari-cusis an enantioselective enzyme that cleaves S-amides. We report here that this enzyme also converts nitriles in the corresponding organic acid, simi-larly to the well characterized amidase from Rhodococcus rhodochrousJ1. The archaeal and rhodococcal enzymes belong to the signature amidases and contain the typical serine-glycine rich motif. They work at different optimal temperature, share a high sequence similarity and both contain an additional CX3C motif. ...

The membrane associated proteins in eicosanoid and glutathione metabo-lism (MAPEG) superfamily includes structurally related membrane proteins with diverse functions of widespread origin. A total of 136 proteins belong-ing to the MAPEG superfamily were found in database and genome screenings. The members were found in prokaryotes and eukaryotes, but not in any archaeal organism.
