An intracelluar actin motor in bacteria?

Article Abstract:

Based on the findings that actin filaments are dynamic structures in two bacterial species, proposing that actins perform motor functions rather than a purely structural role in bacteria. Suggesting that an intracellular motor exists in bacteria that could be derived from an ancestral actin motor that is present in cells early in evolution.

Phylogeny of gamma-proteobacteria: resolution of one branch of the universal tree?

Article Abstract:

The construction of a highly robust phylogenetic tree for 13 gamma-proteobacteria with the combined alignments of 205 conserved orthologous proteins is discussed. The horizontal gene transfer (HGT) events along with other bacterial partners occurred altering the implicit assumption of gamma-proteobacteria monophyly.

TRIM/RBCC, a novel class of 'single protein RING finger' E3 ubiquitin ligases

Article Abstract:

The implication of tripartite motif (TRIM) or really interesting gene RING-B-box-coiled-coil (RBBC) proteins in ubiquitination involving the ligase enzyme (E3) is investigated. The study indicates that the TRIM or RBBC proteins represent the largest class of single protein RING-finger E3 ubiquitin ligases.
