M. Liebergesell et A. Steinbuchel, NEW KNOWLEDGE ABOUT THE PHA-LOCUS AND P(3HB) GRANULE-ASSOCIATED PROTEINS IN CHROMATIUM-VINOSUM, Biotechnology letters, 18(6), 1996, pp. 719-724
The isolation of poly(3-hydroxybutyric acid) granules of Chromatium vi
nosum D was re-examined. Beside the PHA synthase and a 17 kDa protein,
a 14 kDa protein was identified as predominant granule-associated pro
tein. The M(r) as well as the N-terminal amino acid sequence exhibited
identity to ORF5(Cv), which is located within the pha-locus of C. vin
osum. In addition, sequence alignements revealed new information about
ORF4(Cv), which is also located within the pha-locus, and about the 1
7 kDa protein, which exhibited homology to heat shock proteins recentl
y detected in Escherichia coli.
