    Notes: Abstract Five extracellular PHB depolymerases of bacteria isolated from various sources were purified to electrophoretic homogeneity and compared with known extracellular PHB depolymerase fromAlcaligenes faecalis T1. The molecular mass of these enzymes were all around 40–50 kDa. Nonionic detergent, diisopropylfluorophosphate and dithiothreitol inhibited the PHB depolymerase activity of all these enzymes. Trypsin abolished PHB depolymerase activity, but not theD-3-hydroxybutyric acid dimer hydrolase activity of all the enzymes. These results showed that the basic properties of these PHB depolymerases resemble those of theA. faecalis T1 enzyme. Analysis ofN-terminal amino acid sequence of the purified enzymes revealed that these enzymes includingA. faecalis T1 enzyme fall into three groups.

    Pigments of Rubrobacter radiotolerans (1994)
    Springer
    Archives of microbiology 162 (1994), S. 414-421 
    Details
    ISSN: 1432-072X
    Keywords: Key words     Carotenoid ; Bacterioruberin ; Red pigment ; Radiotolerance ; Rubrobacter radiotolerans
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract      The highly radioresistant Rubrobacter radiotolerans, contains red pigments. Since the pigments could not be extracted by usual methods, a new method was developed in which the pigments were extracted with organic solvents after addition of 10 N KOH to the intact cells, followed by neutralization. These pigments were also extracted after treatment with achromopeptidase, but not with lysozyme. The extracted pigments separated into two main spots by TLC (48.6% and 22.6%), and were confirmed to be carotenoids by chemical tests. The two major pigments had 13 conjugated double bonds as determined from the main maximum wavelength of the light absorption spectra. Their molecular weights were determined to be 740 and 722 by mass spectrometry. The mass spectra of their TMS-derivatives revealed that they contained four and three tertiary OH groups, respectively. Confirming their identical light and IR spectra, these pigments were determined to be bacterioruberin and monoanhydrobacterioruberin, respectively, the characteristic carotenoids of halophilic bacteria. The existence of these pigments in bacteria other than halobacteria provides interesting new evidence on the distribution of these compounds.
