The need for an effective oral therapy for leishmaniasis is addressed through the study of the target N-myristoyltransferase from Leishmania major.
The room-temperature structure of lysozyme is determined using 40000 individual diffraction patterns from micro-crystals flowing in liquid suspension across a synchrotron microfocus beamline.
The PDB_REDO pipeline aims to improve macromolecular structures by optimizing the crystallographic refinement parameters and performing partial model building. Here, algorithms are presented that allowed a web-server implementation of PDB_REDO, and the first user results are discussed.
The mechanism of dense vertically aligned carbon nanotube growth achieved by a recently developed thermal chemical vapor deposition method was studied using synchrotron radiation spectroscopic techniques.
The Long-Range Synthon Aufbau Module (LSAM) concept is utilized in the crystal engineering of 1:1 cocrystals of trichlorophenols and halogen-substituted anilines. NMR studies show the presence of LSAMs in solution and also the sequence of association of hydrogen bonding and π⋯π stacking interations that constitute the LSAMs.
MAT2 complex is expressed in nearly all tissues and is essential in providing the necessary SAMe flux for methylation of DNA and various proteins including histones. X-ray crystallography and solution X-ray scattering structures of this complex show an unexpected stoichiometry, offering a unique mechanism of regulation and thus providing a gateway for structure-based drug design in anticancer therapies including liver disease.
Crystal structures of N-myristoyltransferase with four distinct Leishmania-selective small-molecule inhibitors identify key binding-site residues and suggest strategies to design compounds with increased affinity.
