Cover illustration: A small molecule inhibitor at the active site of E. coli methionine aminopeptidase. This inhibitor shows remarkable selectivity towards the MnII-form of the enzyme (p. 425). MnII ions are the two partially exposed green spheres. |

Synopsis: The structure of T. reesei hydrophobin HFBII is described to an ultrahigh resolution of 0.75 Å. The structure has been carefully analyzed and comparison is made to a previously published atomic resolution structure of the same protein as well as to other ultrahigh-resolution protein structures found in the PDB.

Synopsis: When a strict sampling handling protocol is respected, low-temperature absorption spectra of three-dimensional bR crystals, grown in lipidic cubic phase, are almost identical to those obtained for purple membrane. Slight changes of the crystal hydration lead to drastic and irreversible modifications of the spectrum that are to be avoided in the context of high-resolution crystallography.

Synopsis: The crystal-to-crystal phase transition of monoclinic hen egg-white lysozyme mediated by dehydration proceeds by way of an intermediate state containing two types of microcrystals: original and transformed. The enhancement of the diffraction power of the transformed crystal is mostly ascribable to the suppression of rigid-body motion in the densely packed crystal.

Synopsis: A method has been developed to obtain candidate conformations of multidomain proteins for use in molecular replacement. After obtaining the relative rotation between domains, iterative normal-mode analysis was used to drive the template structure near to the target conformation.

Synopsis: The structure of the complex formed between phospholipase A2 (PLA2) and diclofenac revealed the substrate-binding site of PLA2 to be physically blocked by diclofenac with a strong affinity, making several interactions with the enzyme. Surface plasmon studies indicated a value of 4.8 × 10-8 M for the dissociation constant (Kd).

Synopsis: The TLSMD algorithm finds an optimal multi-group TLS (translation/libration/screw) description of a protein as seen in a single crystal structure. This description is an approximation to intrinsic dynamic properties of the protein such as interdomain motion and local flexibility. TLSMD-generated models can improve crystallographic refinement and can offer insight into biologically relevant dynamic properties of the protein.
