Cloned(Commentary)

Cloned (Comment) Organism
overexpression of SuSy in transgenic plants Solanum tuberosum

Protein Variants

Protein Variants Comment Organism
additional information construction of transgenic enzyme overexpressing plants and of transgenic antisense plants. ADPG diphosphorylase and UDPG diphosphorylase activities in tubers from overexpressing plants are significantly higher than in control tubers, whereas ADPG diphosphorylase activities in tubers of one SuSy line are significantly lower than in control tubers Solanum tuberosum

General Information

General Information Comment Organism
metabolism the enzyme is important in starcj biosynthesis in potato tubers, changes in SuSy activity do not affect the expression of genes directly involved in starch metabolism, but might lead to important changes in the tuber metabolome and N -glycome Solanum tuberosum
