WebHomoserine is phosphorylated, and threonine synthase catalyzes a complex reaction that converts the resulting homoserine phosphate to threonine. Aspartokinase-homoserine dehydrogenase I is the major homoserine dehydrogenase activity. Threonine allosterically inhibits its activity. damper zz-r 価格
