abstract = {Zinc (Zn(2+)) deficiency causes retinal dysfunctions such
as night blindness and neurodegeneration. Because Zn(2+)
binds directly to the photoreceptor rhodopsin and alters its
stability, the stabilization of rhodopsin may be key to
prevention and treatment of retinal dysfunctions. In this
paper, we investigated if not only trace metals but also
other nutrients may stabilize rhodopsin structure in vitro.
Detailed studies of the thermal stability of secondary and
tertiary structure of rhodopsin in the presence and absence
of the chlorophyll derivative chlorin e6 alone and together
with bivalent metal ions Zn(2+), Cu(2+), Fe(2+), Ni(2+),
Mg(2+)and Mn(2+) over a temperature range 5-100 degrees C
were conducted using circular dichroism and fluorescence
spectroscopy. When both chlorin e6 and Zn(2+) are present, a
pronounced increase in the thermal stability of overall
secondary structure content is observed compared to either
compound alone. This additive capacity is also noted with
Cu(2+), but not when other metal ions and chlorin e6 are
combined.},
