CC   -!- FUNCTION: Antenna protein that modulates the color of the
CC       bioluminescence emission of the luciferase. In the presence of LumP,
CC       luciferase emission is shifted to higher energy values (shorter
CC       wavelength).
CC   -!- COFACTOR:
CC       Name=6,7-dimethyl-8-(1-D-ribityl)lumazine; Xref=ChEBI:CHEBI:58201;
CC       Note=Binds 1 6,7-dimethyl-8-(1'-D-ribityl)lumazine non-covalently.;
