IMMUNOCYTOCHEMICAL ANALYSIS OF POLY-BETA-HYDROXYBUTYRATE (PHB) SYNTHASE IN ALCALIGENES-EUTROPHUS H16 - LOCALIZATION OF THE SYNTHASE ENZYME AT THE SURFACE OF PHB GRANULES
Tu. Gerngross et al., IMMUNOCYTOCHEMICAL ANALYSIS OF POLY-BETA-HYDROXYBUTYRATE (PHB) SYNTHASE IN ALCALIGENES-EUTROPHUS H16 - LOCALIZATION OF THE SYNTHASE ENZYME AT THE SURFACE OF PHB GRANULES, Journal of bacteriology, 175(16), 1993, pp. 5289-5293
Antibodies raised against the Alcaligenes eutrophus poly-beta-hydroxyb
utyrate (PHB) synthase polypeptide were used for immunocytochemical lo
calization of the synthase enzyme in whole cells and purified PHB gran
ules. The data presented demonstrate for the first time that the synth
ase enzyme is located on the surface of the PHB granule rather than be
ing incorporated inside the granule during its formation. From these b
asic observations and data from the recent literature, a model of gran
ule assembly is proposed.
