Packet 4: Tossup 19

One of these proteins with FMN present in its LOV (“L-O-V”) domain is called iLOV (“eye-L-O-V”). One of these proteins, called UnaG, derived from Japanese eels, binds to the endo-vinyl dipyrrinone of an endogenous ligand. One of these proteins derived from the alpha-allophycocyanin of Trichodesmium erythraeum covalently binds biliverdin. During maturation, a domain in one of these proteins (10[1])undergoes torsional rearrangements before cyclization and oxidation, which is sped up in its superfolder variant. (10[1])Hydrogen peroxide is a byproduct of the auto-oxidation of these proteins to form an HBI moiety from a S65–Y66–G67 (10[2]-5[1])motif (10[1])in the middle of an 11-strand (10[1])beta-barrel. (10[2])Roger Tsien (10[4])engineered (10[2])one of these proteins that was originally isolated by Osamu (10[1])Shimomura. (10[2])For 10 points, name these proteins frequently used as reporters, which were originally discovered (10[1])in jellyfish. ■END■ (10[3])
