Recently, we revealed the architecture of the clamp−loader−helicase (τ-DnaB) complex in Bacillus by atomic force microscopy imaging and constructed a structural model, whereby a pentameric clamp−loader interacts with the hexameric helicase. Crucial to this model is the assumption that the clamp−loader forms a pentamer in the absence of other components of the clamp−loader …

Get a quoteINTRODUCTION. The speed and processivity of DNA synthesis during replication is greatly increased by interaction of the core polymerase with a ring-shaped sliding clamp that encircles double-stranded DNA and slides along it ( 1).In bacteria, this protein is known as the β-clamp and is composed of two β subunits arranged as a head-to-tail ring with 6-fold symmetry ( 2, 3).
Get a quotel-Photo-leucine is a synthetic derivative of the l-leucine amino acid that is used as its natural analog and is characterized for having photo-reactivity, which makes it suitable for observing and characterizing protein-protein interactions (PPI). When a protein containing this amino acid (A) is lightened with ultraviolet light while interacting with another protein (B), the complex formed

SLRPs bind to collagens and regulate collagen fibril growth and fibril organization. SLRPs also interact with various cytokines and extracellular compounds, which lead to various biological functions such cell adhesion and signaling, …

In agreement with our mutagenesis experiments, these data also suggest that the presence of an intact linker region that connects the N‐ and C
