CCP4
This article describes the Collaborative Computational Project No. 4 (CCP4). It is intended as a general literature citation for the use of the CCP4 software suite in structure determination.
research papers
The design, validation, proof of mechanism and exploitation of a surface-entropy reduction mutant to solve the structure of the benchmark inhibitor Nutlin-3a bound to the cancer drug-discovery target MDM2 are reported.
abstracts
research papers
A public web-based facility to infer, analyse and graphically represent the likely modes of a protein motion, starting from a static structure, is presented.
research papers
This paper presents a survey of techniques that explore the surface properties of protein:protein interfaces so as to inform the prediction of probable sites of protein:protein interaction on newly determined protein structures.

The structure of HsaD, a carbon-carbon bond serine hydrolase involved in steroid catabolism that is critical for the survival of M. tuberculosis inside human macrophages, has been solved by X-ray crystallography. Data were collected at the Diamond Light Source in Oxfordshire, England: this paper describes one of the first structures determined at the new synchrotron.
research papers
The structures of Dsk2 UBL, Dsk2 UBA and their complex are described. The complex explains the reduced affinity of the UBA domain for UBL compared with that for ubiquitin.
CCP4
A brief overview of techniques used in the hit-identification/validation stage of drug discovery is given, highlighting the importance of orthogonal measurements and triangulation in early-stage crystallographic hit validation.
research papers
The CCP4 molecular-graphics program now uses the Qt framework to provide a modern look and feel. There are many new features including rendering for publication-quality images and sequence alignment.

The structure of triosephosphate isomerase (TIM) from the organism Escherichia coli has been determined at a resolution of 2.6 Å. The structure was solved by the molecular replacement method, first at 2.8 Å resolution with a crystal grown by the technique of hanging-drop crystallization from a mother liquor containing the transition-state analogue 2-phosphoglycolate (2PG). As a search model in the molecular replacement calculations, the refined structure of TIM from Trypanosoma brucei, which has a sequence identity of 46% compared to the enzyme from E. coli, was used. An E. coli TIM crystal grown in the absence of 2PG, diffracting to 2.6 Å resolution, was later obtained by application of the technique of macro-seeding using a seed crystal grown from a mother liquor without 2PG. The final 2.6 Å model has a crystallographic R factor of 11.9%, and agrees well with standard stereochemical parameters. The structure of E. coli TIM suggests the importance of residues which favour helix initiation for the formation of the TIM fold. In addition, TIM from E. coli shows peculiarities in its dimer interface, and in the packing of core residues within the β-barrel.
