  • Active-site- and substrate-specificity of Thermoanaerobium Tok6-B1 pullulanase.

    Plant, Adrian R.; Clemens, Robyn M.; Morgan, Hugh W.; Daniel, Roy M. (1987)
    Thermoanaerobium Tok6-B1 pullulanase (EC 3.2.1.41) was active on alpha 1-6-glucosidic linkages of pullulan, amylopectin and glycogen and the alpha 1-4 linkages of amylose, amylopectin and glycogen but not of pullulan. ...
  • The activity of family 11 xylanases at alkaline pH

    Gibbs, M.D.; Reeves, R.A.; Hardiman, E.M.; Choudhary, P.R.; Daniel, Roy M.; Bergquist, Peter L. (Elsevier, 2010)
    Xylanases have several industrial uses, particularly in baking, modification of animal feed and in pulp bleaching in the paper industry. Process conditions in kraft pulp bleaching generally favour an enzyme that is active ...
  • The alleged absence of ubiquinone from elasmobranchs

    Daniel, Roy M.; Redfearn, E.R. (1966)
    It has recently been suggested (Diplock & Haslewood, 1964) that certain lower vertebrates such as elasmobranchs and crocodylians are lacking in ubiquinone. Also, in a study of the lesser-spotted dogfish (Scyliorhinus ...
  • Anaerobic growth and denitrification by Rhizobium japonicum and other rhizobia

    Daniel, Roy M.; Smith, I.M.; Phillip, J.A.D.; Ratcliffe, H.D.; Drozd, J.W.; Bull, A.T. (1980)
    The product of nitrate respiration in Rhizobium japonicum and a number of other rhizobia capable of anaerobic growth utilizing nitrate was N2O. No N2 or ammonia was formed. Nitrate reduction was linked to ATP formation ...
  • Anaerobic growth, nitrate reduction and denitrification in 46 rhizobium strains

    Daniel, Roy M.; Limmer, A.W.; Steele, K.W.; Smith, I.M. (1982)
    A total of 46 rhizobial strains were assessed for anaerobic growth in the presence of nitrate, and, using the criteria of nitrate utilization and nitrous oxide and nitrogen production, for their ability to denitrify. Nitrite ...

  • Comparative characterisation of esterases and lipases for biosensors

    Lind, Penelope A. (The University of Waikato, 2002)
    Twenty four carboxylesterases and lipases from various microbial sources were compared with commercial pig liver esterase in order to determine which would be most appropriate for use in a biosensor application and in the ...
  • The activity and dynamics of enzymes

    Dunn, Rachel V. (The University of Waikato, 2002)
    It is generally accepted that enzymes require internal flexibility, or the activation of anharmonic motions, for catalytic activity. However, in general, the timescales and forms of the functionally important motions coupled ...
  • Evidence for a third thermal parameter of enzymes

    Peterson, Michelle E. (The University of Waikato, 2005)
    This thesis describes tests of a new hypothesis describing the effect of temperature on enzyme activity. Traditionally, the dependence of enzyme activity on temperature has been described by a model (the 'Classical Model') ...
  • Microbial abundance and diversity surrounding mummified seals in Miers Valley, Antarctica

    Robson, Lisa Marie (The University of Waikato, 2004)
    The presence of a number of mummified seal carcasses have been reported in the Dry Valleys of Antarctica. The location of seal carcasses were observed up to 240km in-land, and approximately 1500m above sea level. The ...
  • Antarctic bacteria and enzyme temperature optima

    Hawkins, Sarah Kate (The University of Waikato, 2003)
    The temperature optimum of enzyme activity, as recently described by Daniel et al. (2001), is thought to play a central role in the adaptation of an enzyme to its environmental temperature. The aim of this research was to ...
