Functional flavin receptors. Bis-melamine derivatives bearing a guanidinium ion which bind 6-azaflavin and a thymine-linked substrate through hydrogen bonds in chloroform
Bis-melamine derivatives bearing a guanidinium ion bind 6-azaflavin via five hydrogen bonds and an NADH model having a thymine moiety via three H-bonds in CHCl3, resulting in the rate acceleration due to the proximity effect.
