The amino acids that are key for this change are CYG bicyclic chromophore which is formed spontaneously from Cys 62, Tyr 63, and Gly 64. There are also changes in conformation of four additional amino acids that are near the chromophore, Arg 66, Ser 142, Val 157, and His 193<ref> Biochem J. (2007) 402, 35-42 </ref>. | ||
