Granule-bound starch synthase翻译
Webgranule-bound and soluble starch synthases is an artifi cial one. The embryo has a 59-kDa, exclusively granule bound starch synthase which is very similar in predicted primary sequence to Waxy and Amf gene products. How ever, it also has a starch synthase of 77 kDa which ac counts for most of the soluble activity and which is also granule-bound. WebJun 1, 2008 · An enzyme responsible for amylose synthesis in vivo is granule-bound starch synthase (GBSS), which is usually found as a starch synthase isozyme bound to or embedded in starch granules. In rice, GBSSI is encoded by the Wx gene (Okagaki 1992, Hirose and Terao 2004) which has two functional alleles, Wxa and Wxb (Sano 1984 ).
