Expression

Organism Comment Expression
Solanum tuberosum isoform GWD1 expression reaches its maximum after 10 h of illumination, The lowest expression of isoform GWD1 occurs 4 h after turning the light on, and it is approximately 7times lower than the expression measured 6 h late up

General Information

General Information Comment Organism
metabolism GWD1 phosphorylates highly ordered, insoluble starch, and glucan phosphorylation at the C-6 position results in a transition state of the phosphoglucans,´which is less ordered but still insoluble. This specific state of the starch granule is an appropriate substrate for phosphoglucan, water dikinase GWD3 catalysis (C-3 phosphorylation) after which the phosphoglucan finally becomes soluble Solanum tuberosum
