additional information
-
the enzyme is localized at thylakoid membranes in mature chloroplasts. Under certain light conditions, e.g. far-red light, the increase in PSY mRNA and protein levels is not accompanied by an increase in enzymatic activity. Under these conditions the enzyme is localized in the prolamellar body fraction in a mostly enzymatically inactive form. Subsequent illumination of dark-grown and/or in far-red light seedlings with white light causes the decay of these structures and a topological relocalization of PSY to developing thylakoids which results in its enzymatic activation. The light-dependent mechanism of regulation may contribute to ensuring a spatially and temporally coordinated increase in both carotenoid and chlorophyll contents

ATP
-
Mn2+ and ATP are essential for catalytic activity, the effect is stoichiometric from 0.5-2 mM. Km for ATP is 2.0 mM
