Definition:	A nucleobase analogue that is uracil substituted with a (1,4-dideoxy-D-ribityl)amino group at position 6 and an (E)-(2-oxopropylidene)amino group at position 5; one of 20 modifications to the potent microbial riboflavin-based metabolite antigen 5-(2-oxopropylideneamino)-6-D-ribityl aminouracil (5-OP-RU), an activator of mucosal-associated invariant T (MAIT) cells when presented by the MR1 protein (reported in MED:32123373).
