Forthcoming article in Acta Crystallographica Section F Structural Biology Communications



Acta Crystallographica Section F: Structural Biology Communications is a rapid all-electronic journal, which provides a home for short communications on the crystallization and structure of biological macromolecules. Structures determined through structur



 



Crystal structures of the archaeal RNase P protein Rpp38 in complex with RNA fragments containing a K-turn motif
Crystal structures of the archaeal RNase P protein Rpp38 in complex with RNA fragments containing a K-turn motif are reported.



Solution NMR structures of oxidized and reduced Ehrlichia chaffeensis thioredoxin: NMR-invisible structure owing to backbone dynamics
The overall topology of solution NMR structures of the E. chaffeensis thioredoxin ECH_0218 (Ec-Trx) is similar in the reduced and oxidized states and is similar to other reported thioredoxin structures except that the α-helix (α2) containing the active-site CGPC motif appears shorter in length in the reduced state than in the oxidized state. This outcome of structure calculations is likely to be owing to missing α2 amide resonances in the 1H–15N HSQC spectrum of reduced Ec-Trx owing to backbone dynamics on the millisecond-to-microsecond timescale that prohibit NOE observations or unambiguous NOE assignments in this region of the protein.



Structure of the mouse acidic amino-acid decarboxylase GADL1
The structure of the mouse glutamic acid decarboxylase-like protein 1 (GADL1) is described. The structure provides new insights into the function of GADL1 and related decarboxylases.






Production, biophysical characterization and initial crystallization studies of the N- and C-terminal domains of DsbD, an essential enzyme in Neisseria meningitidis
The cloning, purification, biophysical characterization, crystallization and X-ray diffraction analysis of the two periplasmic domains of N. meningitidis DsbD, a disulfide reductase that is essential for the viability of this human pathogen, are reported.






Structure and stability of the Human respiratory syncytial virus M2–1 RNA-binding core domain reveals a compact and cooperative folding unit
A high-resolution crystal structure of the M2–1 RNA-binding domain of Human syncytial respiratory virus was determined. A combination of crystallography and SAXS indicated a role in its C-terminal extension.



Structure of aspartate β-semialdehyde dehydrogenase from Francisella tularensis
The crystal structure of aspartate β-semialdehyde dehydrogenase from F. tularensis has been determined.



Crystal structure of cytoplasmic acetoacetyl-CoA thiolase from Saccharomyces cerevisiae
Structural comparison of the apo structure of S. cerevisiae thiolase with the structure of the CoA-bound complex of human mitochondrial acetoacetyl-CoA thiolase raises the alternate hypothesis that its identical ordered conformation is induced by substrate binding.



The novel thermostable cellulose-degrading enzyme DtCel5H from Dictyoglomus thermophilum: crystallization and X-ray crystallographic analysis
In this study, a new endo-β-(1,4)-glucanase isolated from the thermophilic D. thermophilum, denoted DtCel5H, has been identified, produced and crystallized. In addition, it is shown that this enzyme possesses cellulose-degradation activity and is highly thermostable. Structural investigations of this new cellulase will offer the opportunity to design and develop enzymes with optimal biotechnological applications.
