In a general approach to the understanding of protein adaptation to high temperature, molecular models of the closely related mesophilic Streptomyces sp. S38 Xyl1 and thermophilic Thermomonospora fusca TfxA family 11 xylanases were built and compared with the three-dimensional (3D) structures of homologous enzymes. Some of the structural features identified(More)
Xyl1 from Streptomyces sp. S38 belongs to the low molecular mass family 11 of endo-beta-1,4-xylanases. Its three-dimensional structure has been solved at 2.0 A and its optimum temperature and pH for enzymatic activity are 60 degrees C and 6.0, respectively. Aspergillus kawachii xylanase XynC belongs to the same family but is an acidophilic enzyme with an(More)
Plant-based recombinant protein production systems have gained an extensive interest over the past few years, because of their reduced cost and relative safety. Although the first products are now reaching the market, progress are still needed to improve plant hosts and strategies for biopharming. Targeting recombinant proteins toward the extracellular(More)
Endo-beta-1,4-xylanases of the family 11 glycosyl-hydrolases are catalytically active over a wide range of pH. Xyl1 from Streptomyces sp. S38 belongs to this family, and its optimum pH for enzymatic activity is 6. Xyn11 from Bacillus agaradhaerens and XylJ from Bacillus sp. 41M-1 share 85% sequence identity and have been described as highly alkalophilic(More)
To perform a systematic review to establish whether blind injections of the gleno-humeral (GHJ) joint may be an accurate alternative to injections performed imaging guidance, considering multiple anatomical approaches. Our search strategy yielded 478 articles for Scopus, 815 articles for MEDLINE, 128 articles for Cochrane Central Register of Controlled(More)
BACKGROUND Clear information is still lacking on the safety of corticosteroids (GCs) therapy in RA despite six decades of clinical experience. SCOPE We performed a literature search in Ovid MEDLINE from January 2000 to December 2012. Our Population Intervention Comparator Outcomes (PICO) strategy search was: rheumatoid arthritis [Population],(More)
