    Description: Serial femtosecond crystallography using ultrashort pulses from x-ray free electron lasers (XFELs) enables studies of the light-triggered dynamics of biomolecules. We used microcrystals of photoactive yellow protein (a bacterial blue light photoreceptor) as a model system and obtained high-resolution, time-resolved difference electron density maps of excellent quality with strong features; these allowed the determination of structures of reaction intermediates to a resolution of 1.6 angstroms. Our results open the way to the study of reversible and nonreversible biological reactions on time scales as short as femtoseconds under conditions that maximize the extent of reaction initiation throughout the crystal.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4361027/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4361027/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tenboer, Jason -- Basu, Shibom -- Zatsepin, Nadia -- Pande, Kanupriya -- Milathianaki, Despina -- Frank, Matthias -- Hunter, Mark -- Boutet, Sebastien -- Williams, Garth J -- Koglin, Jason E -- Oberthuer, Dominik -- Heymann, Michael -- Kupitz, Christopher -- Conrad, Chelsie -- Coe, Jesse -- Roy-Chowdhury, Shatabdi -- Weierstall, Uwe -- James, Daniel -- Wang, Dingjie -- Grant, Thomas -- Barty, Anton -- Yefanov, Oleksandr -- Scales, Jennifer -- Gati, Cornelius -- Seuring, Carolin -- Srajer, Vukica -- Henning, Robert -- Schwander, Peter -- Fromme, Raimund -- Ourmazd, Abbas -- Moffat, Keith -- Van Thor, Jasper J -- Spence, John C H -- Fromme, Petra -- Chapman, Henry N -- Schmidt, Marius -- P41 GM103543/GM/NIGMS NIH HHS/ -- R01GM095583/GM/NIGMS NIH HHS/ -- R24 GM111072/GM/NIGMS NIH HHS/ -- R24GM111072/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 5;346(6214):1242-6. doi: 10.1126/science.1259357.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Physics Department, University of Wisconsin, Milwaukee, WI 53211, USA. ; Department of Chemistry and Biochemistry, Arizona State University, Tempe, AZ 85287, USA. ; Department of Physics, Arizona State University, Tempe, AZ 85287, USA. ; Linac Coherent Light Source, SLAC National Accelerator Laboratory, Sand Hill Road, Menlo Park, CA 94025, USA. ; Lawrence Livermore National Laboratory, Livermore, CA 94550, USA. ; Centre for Ultrafast Imaging, University of Hamburg, 22761 Hamburg, Germany. ; Center for Free Electron Laser Science, Deutsches Elektronen Synchrotron DESY, Notkestrasse 85, 22607 Hamburg, Germany. ; Hauptman-Woodward Institute, State University of New York at Buffalo, 700 Ellicott Street, Buffalo, NY 14203, USA. ; Centre for Ultrafast Imaging, University of Hamburg, 22761 Hamburg, Germany.

    Notes: Abstract The following peptide structure in 3 of 5 coronaro-constrictory peptide factors isolated from bovine hypothalamus was determined by amino acid analysis and Edman degradation: 1) (P1)-Val-Val-Tyr-Pro-Trp; 2) (P2)-Val-Val-Tyr-Pro-Trp-Thr; 3) (P3)-Leu-Val-Val-Tyr-Pro-Trp-Thr. A computer search for these amino acid sequences revealed that these peptides represent fragments 33-37; 33-38; 32-38 of the β-chain of bovine hemoglobin. Solid phase peptide synthesis of 2 peptides (P2 and P3) was carried out. It was established that synthetic peptides had the properties of coronaro-constrictory peptides. The possibility of the formation of hypothalamic coronaro-constrictory peptides in vivo is discussed.

    Notes: High resolution two-dimensional gel electrophoresis (2-DE) using immobilized pH gradients was used to map the tissue-specific polypeptides of the desert locust, Schisiocerca gregaria. Highly specific comprehensive 2-DE reference maps (“master gels”) were developed for the brain, corpus cardiacum, subesophageal ganglion, and hemolymph. The polypeptides were well resolved within the pH 4-7 range in the first dimension and within the 14-94 kDa molecular mass range in the second dimension.

    Notes: High resolution two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) was applied to cultured neonatal rat heart muscle cells, incubated for 72 h at 37°C in serum-free medium, either in the absence or in the presence of 0.1 μM norepinephrine. After silver staining, about 340 and 550 protein spots could be seen in cardiomyocytes, cultured either in the absence or presence of norepinephrine. Of these spots, 141 could be further characterized according to isoelectric point and molecular weight, with 71 protein spots being present under both conditions. In cells cultivated in presence of norepinephrine, 58 new protein spots appeared, whereas 12 spots disappeared, and 22 spots increased (whereas 3 spots decreased) in intensity. In comparison with 2-D PAGE of rat cardiomyocytes, the protein pattern of the intact heart of neonatal rats is incongruent. 2-D PAGE of polypeptides of cultured neonatal rat cardiomyocytes may be a suitable tool to study the regulation of protein synthesis by various stimuli with relevance to cardiac growth adaptation, inotropy and heart failure.

    Notes: The human ciliary neurotrophic factor (CNTF) gene was identified and cloned, based on homology with the recently cloned rat cDNA. The gene encodes a protein of 200 amino acids, which shares about 80% sequence identity with rat and rabbit CNTF and, like these homologues, lacks an apparent secretion signal sequence. The human CNTF gene, like the rat gene, appears to contain a single intron separating two protein coding exons. An intronless human CNTF gene was constructed by the use of polymerase chain reactions and introduced into vectors designed for expression of foreign proteins in E. coli. The rat CNTF gene was also introduced into similar vectors. Both the human and rat proteins were expressed at exceptionally high levels, at 20–40% and 60–70% of total protein, respectively. Extraction of the recombinant proteins from inclusion bodies by guanidinium chloride, followed by two column chromatography steps, produced high yields of pure CNTF that supported survival and neurite outgrowth from embryonic chick ciliary neurons in culture. The biological activity of both recombinant proteins was comparable to that of native rat CNTF.
