    Notes: Cyanophycin is a high molecular weight co-polymer of aspartate and arginine, hitherto considered characteristic of all cyanobacteria. Chemical analysis and radioisotopic incorporation procedures have shown that precipitable cyanophycin is absent from the five species of Synechococcus tested, including the marine Synechococcus WH7803 (type DC2). The implications with respect to the role of cyanobacterial nitrogen reserves are discussed.

    Notes: Abstract Three constitutive forms of Superoxide dismutase activity have been demonstrated in the cyanobacterial marine picoplankter Synechococcus sp. WH 7803 using polyacrylamide gel activity staining techniques. A protein which gave a positive non-haem iron stain on native polyacrylamide gels exhibited N-terminal similarity to both the iron Superoxide dismutase and the manganese Superoxide dismutase of Escherichia coli. The metal prosthetic group of each of the three activity bands was characterised by analysing their differential sensitivities to 5 mM H2O2, 2 mM cyanide and 2 mM of the copper chelator diethyldithiocarbamate. Three distinct Superoxide dismutase activities were observed, an iron Superoxide dismutase, a copper/zinc Superoxide dismutase and a third form which has not been identified. Growth of Synechococcus cells in ASW medium containing no added iron resulted in no alteration in the activity of the iron Superoxide dismutase. Growth of cultures in the absence of copper or zinc resulted in differential changes in the activities of the copper/zinc Superoxide dismutase and the unidentified Superoxide dismutase.

    A comparison of gene organization in the zwf region of the genomes of the cyanobacteria Synechococcus sp. PCC 7942 and Anabaena sp. PCC 7120 (1995)

    Notes: Abstract The region of the genome encoding the glucose-6-phosphate dehydrogenase gene zwf was analysed in a unicellular cyanobacterium, Synechococcus sp. PCC 7942, and a filamentous, heterocystous cyanobacterium, Anabaena sp. PCC 7120. Comparison of cyanobacterial zwf sequences revealed the presence of two absolutely conserved cysteine residues which may be implicated in the light/dark control of enzyme activity. The presence in both strains of a gene fbp, encoding fructose-1,6-bisphosphatase, upstream from zwf strongly suggests that the oxidative pentose phosphate pathway in these organisms may function to completely oxidize glucose 6-phosphate to CO2. The amino acid sequence of fructose-1,6-bisphosphatase does not support the idea of its light activation by a thiol/disulfide exchange mechanism. In the case of Anabaena sp. PCC 7120, the tal gene, encoding transaldolase, lies between zwf and fbp.

    Notes: Abstract The nucleotide sequences of the class I phycoerythrin (PE) α-and β-subunit genes (cpeA and cpeB) from the marine cyanobacterium Synechococcus sp. WH7803 are reported. The cpeB gene is located upstream of cpeA with a separation of 56 nucleotides and the two genes are co-transcribed as a transcript of 1.3 kb, with the transcription startpoint being localized to 110–111 bp upstream of cpeB. The sequence of the promoter region bears no similarity to promoters reported for other cyanobacterial PE genes. Pentanucleotide repeats found upstream of some PE operons, particularly in the case of cyanobacterial strains capable of chromatic adaption, are not found in Synechococcus sp. WH7803; instead the sequence 5′-CGGTT-3′ is repeated three times in the promoter region.

    Notes: Summary The smooth endoplasmic reticulum (ER) and cytosol fractions of liver homogenates exhibit phosphoprotein phosphatase activity towards glycogen synthase D and phosphorylase a. The following observations suggest that liver contains multiple forms of these phosphatases. Synthase phosphatase activity in either fraction was more readily inactivated by heating than phosphorylase phosphatase activity. Both synthase phosphatase and phosphorylase phosphatase activities in smooth ER were non-competitively inhibited by Mg2+, but were activated by this ion in the cytosol. Synthase phosphatase activities in cytosol and smooth ER were stimulated by a number of sugar phosphates, particularly glucose-l-phosphate, galactose-6-phosphate and fructose-6-phosphate. Erythrose-4-phosphate stimulated synthase phosphatase activity in the cytosol, but inhibited the microsomal enzyme. Phosphorylase phosphatase activities in either fraction were inhibited by most sugar phosphates. Adenosine mono-, di- and tri-phosphates inhibited phosphatase activities in both fractions. Low concentrations of AMP and ADP inhibited phosphorylase phosphatase activities to a greater extent than synthase phosphatase activities. Chromatography of the smooth ER fraction on DEAE-cellulose resulted in the separation of synthase phosphatase from phosphorylase phosphatase, as soluble proteins. The elution profile for the microsomal phosphatase was different from that for the cytosol enzymes. It is concluded that: (a) both synthase phosphatase and phosphorylase phosphatase in liver have at least two isoenzyme forms (b) synthase phosphatase and phosphorylase phosphatase are separate enzymes (c) the different behaviour of microsomal and cytosol phosphatases towards divalent cations and sugar phosphates provides a potential mechanism for the differential regulation of these activities in liver.

    Notes: Abstract The N-terminal part sequences of pituitary growth hormone, Nα-acetyl-hGH 7–13 and hGH 6–13, promoted conversion of glycogen synthase b to glycogen synthase a in skeletal muscle and adipose tissue when injected intravenously. The peptides also caused conversion of phosphorylase a to phosphorylase b in liver and adipose tissue, but not in muscle, where the peptides antagonised activation of phosphorylase. Synthase phosphatase activity in muscle and phosphorylase phosphatase activity in liver increased after injection of peptide, with time courses of change similar to those seen for muscle synthase and liver phosphorylase activities. Injection of peptide also decreased both the cyclic AMP dependent and independent synthase kinase activities in muscle. These results show that the insulin-like activities of these peptides on glycogen synthase and phosphorylase involve both increases in protein phosphatase activities and inhibition of protein kinase activities. These results are discussed in relation to the insulin-like activities of growth hormone.

    Shear zones in the upper mantle: evidence from alpine- and ophiolite-type peridotite massifs (2007)
    In:  Geological Society Special Publication 224: 11-24.
    Details
    Publication Date: 2007-10-08
    Description: There is abundant field and microstructural evidence for localization of deformation in alpine- and ophiolite-type mantle massifs. On the basis of field relationships and microstructures we recognize two types of tectonite shear zones (medium- to coarse- and fine-grained), as well as two types of mylonitic shear zones (anhydrous and hydrous peridotite mylonites). In tectonite shear zones, softening processes responsible for localization are probably melt-related weakening in the medium to coarse tectonites and a change in limiting slip system in the fine-grained tectonites. In peridotite mylonites, the most likely cause for softening and localization is a change in dominant deformation mechanism from dislocation to grain size sensitive creep. Microstructural and petrological study of mylonite rocks reveals that reactions, either continuous net-transfer reactions (anhydrous and hydrous) or melt-rock reactions, play a key role in the formation of fine-grained material that promotes grain size sensitive creep. These reactions occur over a broad range of pressure-temperature conditions encompassing a large part of the lithospheric upper mantle. We conclude that mantle shear zones are widespread and that they reduce the (bulk) strength of the lithosphere significantly.
