Inhibition of HIV-1 replication by primer RNA packaging inhibitors

ABSTRACT An essential step in the life cycle of human immunodeficiency virus type 1 (HIV-1) is the packaging of tRNA 3 Lys during viral assembly. This step, which requires the assembly of a ternary complex consisting of GagPol, mitochondrial lysyl…

A Rac-specific competitive inhibitor of guanine nucleotide binding reduces metastasis in triple-negative breast cancer

• A41 is a specific and reversible inhibitor of RAC proteins • A41 competes with guanine nucleotide binding • A41 blocks RAC1 activity and RAC1-dependent cell functions in cancer cells • A41 exhibits anti-metastatic effects and increase of the…

Structural Basis for Parallel G-Quadruplex Recognition by an Ankyrin Protein

G-Quadruplex (G4) structures formed by guanine-rich DNA and RNA sequences are implicated in various biological processes. Understanding the mechanisms by which proteins recognize G4 structures is crucial for elucidating their functional roles. Here…

Estimating mutation rates under heterogeneous stress responses

Exposure to environmental stressors, including certain antibiotics, induces stress responses in bacteria. Some of these responses increase mutagenesis and thus potentially accelerate resistance evolution. Many studies report increased mutation rates…

Extended Sampling of Macromolecular Conformations from Uniformly Distributed Points on Multidimensional Normal Mode Hyperspheres

Proteins are dynamic entities that adopt diverse conformations, which play a pivotal role in their function. Understanding these conformations is essential, and protein collective motions, particularly those captured by normal mode (NM) and their…
