If small molecules have led to tremendous progress in curing diseases, new therapeutic agents such as peptides or antibody-drugs conjugates have emerged as a highly promising next generation of pharmaceuticals. As for small molecules, their derivatization ...
Designing compounds that bind to the acidic patch of the nucleosome core particle (NCP) is an emerging therapeutic approach that can inhibit the binding of key chromatin factors. Pretreatment of human ovarian carcinoma, A2780, cells with RAPTA-T, an antime ...
Inspired by the preferential, allosteric binding of RAPTA-T and auranofin to the nucleosome core particle, we describe the design and synthesis of a series of heterobimetallic ruthenium(II)-gold(I) complexes with varying spacer lengths ranging from four to ...
Interactions of transmembrane (TM) helices play a key role in many cell processes. The configuration and cross angle these helices adopt are traditionally attributed to specific residue interactions. We present a different approach, in which specific resid ...
The packing structures of transmembrane helices are traditionally attributed to patterns in residues along the contact surface. In this view, besides keeping the helices confined in the membrane, the bilayer has only a minor effect on the helices structure ...
Bacteriophages with contractile tails and the bacterial type VI secretion system have been proposed to use a special protein to create an opening in the host cell membrane during infection. These proteins have a modular architecture but invariably contain ...
The conformational search for favorable intramolecular interactions during protein folding is limited by intrachain diffusion processes. Recent studies on the dynamics of loop formation in unfolded polypeptide chains have focused on loops involving residue ...
Reducing the use of non-renewable fossil energy reserves together with improving the environment are two important reasons that drive interest in the use of bioethanol as an automotive fuel. Conversion of sugar and starch to ethanol has been proven at an i ...
HypA and HypB are maturation proteins required for incorporation of nickel into the hydrogenase large subunit. To examine the functions of these proteins in nickel insertion, the hybF gene, which is a homolog of hypA essential for maturation of hydrogenase ...
Parkinsons disease (PD) is characterized by the loss of dopaminergic neurons in the substantia nigra and the presence of intraneuronal inclusions consisting of aggregated and post-translationally modified a-synuclein (a-syn). Despite advances in the chemic ...
