A fluorometric binding assay for lectin and yeast cells using the avidin-biotin system was previously reported (Y. Oda, M. Kinoshita, and K. Kakehi, Anal. Biochem. 254, 41-48, 1997). However, the true amount of bound lectin could not be determined by

The chromophore of photoactive yellow protein (PYP) (i.e., 4-hydroxycinnamic acid) has been replaced by an analogue with a triple bond, rather than a double bond (by using 4-hydroxyphenylpropiolic acid in the reconstitution, yielding hybrid I) and by a "locked" chromophore
