The first documented study on bacterial predation was carried out using myxobacteria three
quarters of a century ago. Since then, many predatory strains, diverse hunting strategies …

Rho GTPases are key molecular switches controlling the transduction of external signals to
cytoplasmic and nuclear effectors. In the last few years, the development of genetic and …

DIRAS3 is an imprinted tumor suppressor gene that encodes a 26 kDa GTPase with 60%
amino acid homology to RAS, but with a distinctive 34 amino acid N-terminal extension …

Cellular Signal Processing offers a unifying view of cell signaling based on the concept that
protein interactions act as sophisticated data processing networks that govern intracellular …

Rod-shaped Myxococcus xanthus cells are polarized with proteins asymmetrically localizing
to specific positions. This spatial organization is important for regulation of motility and cell …

Photoautotrophic microalgae based biorefinery concepts are currently not competitive
compared to other established production systems. Therefore, innovative upstream …

In contrast to prokaryotes, eukaryotic cells are characterized by a complex set of internal
membrane-bound compartments. A subset of these, and the protein machineries that move …

GTP hydrolysis is a biologically crucial reaction, being involved in regulating almost all
cellular processes. As a result, the enzymes that catalyze this reaction are among the most …

The Ras-like GTPase MglA is a key regulator of front-rear polarity in the rod-shaped
Myxococcus xanthus cells. MglA-GTP localizes to the leading cell pole and stimulates …

The evolution of eukaryotic cellular complexity is interwoven with the extensive
diversification of many protein families. One key family is the ARF GTPases that act in …
