21971443-2	2012	NQO2 includes a flavin adenine dinucleotide (FAD) cofactor, but X-ray crystallographic analysis of human NQO2 expressed in Escherichia coli showed that electron density for the isoalloxazine ring of FAD was weak and there was no electron density for the adenine mononucleotide moiety.	isoalloxazine	177-190	N-ribosyldihydronicotinamide:quinone reductase 2	Homo sapiens	0-4	
26636353-7	2015	In reduced NQO2, ethidium and AO occupied a more peripheral position in the active site, allowing several water molecules to interact with the polar end of the negatively charged isoalloxazine ring.	isoalloxazine	179-192	N-ribosyldihydronicotinamide:quinone reductase 2	Homo sapiens	11-15

15350128-3	2004	All three resveratrol hydroxyl groups form hydrogen bonds with amino acids from QR2, anchoring a flat resveratrol molecule in parallel with the isoalloxazine ring of FAD.	isoalloxazine	144-157	N-ribosyldihydronicotinamide:quinone reductase 2	Homo sapiens	80-83
