| Summary: | Sago palms (Metroxvlon sago Rottb. ) are high in starch and have the potential to sustain the
high demand food and biofuel industry. Studies on sago starch synthase are crucial for better
understanding of sago starch for development and improvement. Five different extraction
buffer, and four protein concentration methods were tested to optimize the extraction of starch
synthase prior to starch synthase assay. GBSS buffer (Denyer et a!., 1995) was found to be the
best extraction buffer. Ultrafiltration and ammonium sulphate precipitation at 80 %(w/v) were
found to be most suitable to concentrate the crude enzyme extracted. Sago trunk of Buhul
growth stage was determinded to contain highest protein. Three distinct bands were observed
on 9% SDS-PAGE; -4OkD, -3lkD and -14.4kD and several faint bands. However, the starch
synthase assay was unable to be conducter due incomplete materials. |
