The paradigmatic transcription factors of the NFκB family provide an increasingly complex view of the mechanism of signal‐mediated transcriptional activation. Although the primary event, phosphorylation and subsequent ubiquitin‐dependent degradation of IκBα, the inhibitor of the canonical...
Biochemistry in Spain owes much to the figure of Alberto Sols. In words of Nobel Prize winner Severo Ochoa: “He has been the first scientist to establish successfully biochemistry in Spain.” His intellectual rigour, care in experimental design, emphasis on quality, and attention to the...
Proteins containing intrinsically disordered (ID) regions are widespread in eukaryotic organisms and are mostly utilized in regulatory processes. ID regions can mediate binary interactions of proteins or promote organization of large assemblies. Post‐translational modifications of ID regions...
Thanks to recent fast progress, NMR is now in a strategic position to provide unique atomic resolution information on a variety of different biological macromolecules in different conditions (solution, solid state, in‐cell). We would like here to present recent developments that enable to focus...
Phototransformable fluorescent proteins (FPs) have received considerable attention in recent years, because they enable many new exciting modalities in fluorescence microscopy and biotechnology. On illumination with proper actinic light, phototransformable FPs are amenable to long‐lived...
Mammalian adrenodoxin (Adx) has been known for many years as an essential electron mediator in mitochondrial cytochrome P450 systems. Because of its ability to support several cytochrome P450 enzymes, it is involved not only in adrenal steroid hormone biosynthesis but also in vitamin D and bile...
One of the hallmarks of life is the widespread use of certain essential ribozymes. The ubiquitous ribonuclease P (RNase P) and eukaryotic RNase MRP are essential complexes where a structured, noncoding RNA acts in catalysis. Recent discoveries have elucidated the three‐dimensional structure of...
The use of atomic force microscopy (AFM) applied to biological systems to generate high resolution images is gaining a wider acceptance. However, the most remarkable advances are being achieved on the use of the AFM to measure inter‐ and intramolecular interaction forces with piconewton...
