| Description | Journal: Journal of Biological Inorganic Chemistry The distribution of dye‐linked l‐malate dehydrogenase (l‐malate: acceptor oxidoreductase, EC 1.1.99.16) was investigated in many thermophilic bacteria. The enzyme occurred widely in thermophilic spore‐forming bacteria like bacilli and thermoactinomycetes. The enzyme was purified to homogeneity from a thermophile, Bacillus sp. DSM 465, with a 2.7% overall recovery by DEAE‐Toyopearl column chromatography, Sephacryl S‐400 column chromatography and preparative slab PAGE. The enzyme had a molecular mass of about 660 kDa and consisted of about ten subunits all with a molecular mass of 66 kDa. The enzyme retained its full activity upon heating at 55°C for at least 60 min and with incubation at pH 5.0–10.0, 55°C, for 10 min. The enzyme exclusively catalyzed l‐malate dehydrogenation in the presence of an electron acceptor such as 2,6‐dichloroindophenol. The Michaelis constants for l‐malate and 2,6‐dichloroindophenol were determined to be 1.67 mM and 0.050 mM, respectively. FAD was identified as a prosthetic group of the enzyme by HPLC. |
