RA Kumar S., Harrylock M., Walsh K.A., Cormier M.J., Charbonneau H.;
RT "Amino acid sequence of the Ca2(+)-triggered luciferin binding protein of
RT Renilla reniformis.";
RL FEBS Lett. 268:287-290(1990).
CC -!- FUNCTION: This Ca(2+)-dependent protein binds to luciferin. The
CC luciferin of LBP is capable of reacting with luciferase and O(2) only
CC when calcium is bound.
