Molecular recognition. 12. Molecular recognition of nucleotides. Concurrent hydrogen bonding and electrostatic interactions in the two-point fixation of flavin mononucleotide.
A pyridinium compound having a bisresorcinol moiety forms a two-point adduct with monoanion of flavin mononucleotide (FMN) in CHCl3–CH3OH (99.7:0.3) via a pyridinium–phosphate electrostatic interaction and an isoalloxazine–bisresorcinol hydrogen bonding.
