| 2.4.1.242 | more |
enzyme is involved in the starch synthesis pathway synthesizing the amylose component, putative mechanism of regulation of GBSSI gene in photosynthetic tissue assuring the steady-state level of the isozyme, circadian oscillations of the mRNA level in leaves during day/night cycle, overview |
Arabidopsis thaliana |

? |
| 2.4.1.242 | more |
isozyme GBSSI synthesizes the amylose component of starch, while isozyme GBSSII does not, due to kinetic differences |
Pisum sativum |

| 2.4.1.242 | more |
isozyme GBSSII has an important function in amylose synthesis in the pericarp of seeds |
Triticum aestivum |

| 2.4.1.242 | more |
the enzyme plays an important role in the synthesis of B2 and B3 chains of amylopectin in pea |
Pisum sativum |
? |
- |
? |
| 2.4.1.242 | more |
isozyme GBSSI in isolated starch granules elongates malto-oligosaccharides progressively, adding more than one glucose molecule for each enzyme-glucan encounter, isozyme GBSSII also elongates malto-oligosaccharides but with lower affinity and not progressively |
Pisum sativum |

? |
| 2.4.1.242 | more |
most effective primer of the reaction is amylopectin, 16% activity with glycogen compared to amylopectin |

| 2.4.1.242 | more |
the 56-kDa protein is an isozyme of the waxy protein in diploid wheat and belongs to the GBSSI family |
Triticum monococcum |
? |
- |
? |
| 2.4.1.242 | more |
the enzyme requires the presence of crystalline amylopectin for granule binding and production of amylose, while unbound enzyme occuring in debranching enzyme mutants are only capable to synthesize amylose-like material |
Chlamydomonas reinhardtii |
