    Suppression of basal insulin secretion by adrenalin in normal man and in patients with insulinomas (1977)

    Notes: Summary Basal insulin secretion has been thought to be via a different mechanism from stimulated insulin secretion, partly because it is not similarly suppressed by adrenalin. However, adrenalin normally causes hyperglycaemia, but if it is infused while the plasma glucose is kept constant there is marked suppression of insulin secretion. Sympathetic stimulation modulates basal insulin secretion, and alpha adrenergic blockade impaired the suppression of insulin secretion in response to hypoglycaemia. Four of five benign insulinomas had marked suppression of insulin secretion by adrenalin, but one malignant and one benign insulinoma had little suppression. Both had a raised proportion of their basal plasma insulin as proinsulin, and the impaired suppression of secretion by adrenalin probably signified an undifferentiated tumour.

    Glutamate oxaloacetate transaminase isozymes of the Triticinae: dissociation and recombination of subunits (1977)
    Springer
    Theoretical and applied genetics 50 (1977), S. 47-51 
    Details
    ISSN: 1432-2242
    Keywords: Glutamate Oxaloacetate Transaminase ; Isozymes ; Triticum aestivum ; Subunits

    Topics: Biology
    Notes: Summary A simple procedure has been developed for the dissociation of active molecules of glutamate oxaloacetate transaminase (GOT: E.C. 2.6.1.1) into protomers and for the reassociation of the subunits into active enzymes. Results of experiments in which the protomers of genetically controlled electrophoretic variants of GOT of Triticum aestivum and of several related species were dissociated and recombined in crude tissue extracts and in partially purified preparations support the hypothesis that the enzyme exists functionally as a dimer in the Triticinae.

    Genetic control of shikimate dehydrogenase in hexaploid wheat (1983)
    Springer
    Biochemical genetics 21 (1983), S. 963-968 
    Details
    ISSN: 1573-4927
    Keywords: shikimate dehydrogenase ; Triticum ; hexaploid wheat ; isozymes ; genetics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The genetics of shikimate dehydrogenase (SKDH; EC 1.1.1.25) was investigated in Triticum aestivum cv Chinese Spring (2n=6x=42; genomic formula ABD) using the zymogram technique. The enzyme occurs in two electrophoretically distinct forms on starch gels. The results of a study of aneuploid derivatives of Chinese Spring indicate that the SKDH isozyme of faster electrophoretic mobility is encoded by a gene, designated Skdh-A1, located in the p (= short) arm of chromosome 5A and that the products of two other genes, designated Skdh-B1 and Skdh-D1, located one each in the p arms of homoeologous chromosomes 5B and 5D, respectively, encode two isozymes of slower and coincident electrophoretic mobility. Additional evidence for this interpretation of the genetic basis of hexaploid wheat SKDH was obtained in studies of the SKDH zymogram phenotypes of various close relatives of hexaploid wheat, including T. monococcum, T. longissimum, T. tauschii, T. turgidum, and T. timopheevii.
