    • Structure and functional characterization of pyruvate decarboxylase from Gluconacetobacter diazotrophicus 

      van Zyl, Leonardo Joaquim; Schubert, Wolf-Dieter; Tuffin, Marla I.; Cowan, Donald A. (BioMed Central, 2014)
      BACKGROUND: Bacterial pyruvate decarboxylases (PDC) are rare. Their role in ethanol production and in bacterially mediated ethanologenic processes has, however, ensured a continued and growing interest. PDCs from ...
    • Structure of an aliphatic amidase from Geobacillus pallidus RAPc8 

      Kimani, Serah W.; Agarkar, Vinod B.; Cowan, Donald A.; Sayed, Muhammed F.; Sewell, B. Trevor (International Union of Crystallography, 2007)
      The amidase from Geobacillus pallidus RAPc8, a moderate thermophile, is a member of the nitrilase superfamily and catalyzes the conversion of amides to the corresponding carboxylic acids and ammonia. It shows both ...
    • The upper temperature for life – where do we draw the line? 

      Cowan, Donald A. (Elsevier, 2004)
      The newly isolated hyperthermophilic archaeal strain 121 grows slowly at 121 8C and even survives short periods at 130 8C. This is another organism that grows best at temperatures well in excess of 100 8C! We should not ...
