TL;DR: A crystal structure of bovine Arp2/3 complex, an assembly of seven proteins that initiates actin polymerization in eukaryotic cells, is determined at 2.0 angstrom resolution and it is predicted that WASp/Scar proteins activate Arp 2-3 complex by bringing Arp1 into proximity with Arp3 for nucleation of a branch on the side of a preexisting actin filament.

TL;DR: The anthocyanins have been identified in the flowers, fruits or leaves of approximately 200 species of plants as mentioned in this paper, and the results have been combined with earlier data, to ascertain the frequency with which derivatives of the three main Anthocyanidin types occur as flower pigments among the species so far examined.

TL;DR: It is proposed that binding Ca2+ can release the connections that join the N- and C-terminal halves of gelsolin, enabling each half to bind actin relatively independently.

TL;DR: The structure of the functional N-terminal domain from the extracellular region of the cell surface receptor sialoadhesin has been determined in complex with the oligosaccharide 3' sialyllactose and provides structural information for the siglec family of proteins.

TL;DR: It is proposed that different mechanisms were selected in bacteria, plants and metazoa, which achieved actin filament compositional variation leading to the expansion of their functional diversity.
