Starch synthase 4

Webb21 okt. 2024 · SS4 plays a key role in granule initiation, allowing it to proceed in a way that avoids premature degradation of primers by starch hydrolases, such as AMY3. SS4 forms dimers, which depends on a region located between the coiled-coil region and the glycosyltransferase domain of SS4. Webb30 juni 2004 · To elucidate the roles of the isogenes encoding starch synthase (EC 2.4.1.21) in rice (Oryza sativa L.), a comprehensive expression analysis of the gene family was conducted. Extensive searches for starch synthase genes were done in the databases of both the whole genome and full-length cDNAs of rice, and ten genes were revealed to …
