Abstract:
Sequence analysis of several cDNAs encoding the phasin protein of Ralstonia eutropha indicated that the carboxyl terminus of the resulting derived protein sequence is different from that reported previously. This was confirmed by: (1) sequencing of the genomic DNA; (2) SDS-PAGE and peptide analysis of wild-type and recombinant phasin; and (3) mass spectrometry of wild-type phasin protein. The results have implications for the model proposed for the binding of this protein to polyhydroxyalkanoic acid granules in the bacterium.
