comparison of the deduced amino acid sequences of sir-fp and nadph-cytochrome p-450 oxidoreductase ( porter , t. d. , and kasper , c.b . ( 1985 ) proc . natl . acad . sci . u. s.a. 82 , 973-977 ) also showed identities that suggest these two proteins are descended from a common precursor , which contained binding regions for both fmn and fad .
