CC   -!- FUNCTION: Involved in the import of queuosine (Q) precursors, required
CC       for Q precursor salvage. Transports 7-cyano-7-deazaguanine (preQ(0))
CC       and 7-aminomethyl-7-deazaguanine (preQ(1)), with a preference for
CC       preQ(0). {ECO:0000269|PubMed:28208705}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_02088, ECO:0000269|PubMed:15919996}; Multi-pass membrane
CC       protein {ECO:0000255|HAMAP-Rule:MF_02088}.
CC   -!- DISRUPTION PHENOTYPE: YhhQ-queD double mutant cannot produce Q modified
CC       tRNA in minimal media with preQ(0) or preQ(1). YhhQ expressed from a
CC       plasmid restores the presence of Q modified tRNA.
CC       {ECO:0000269|PubMed:28208705}.
CC   -!- SIMILARITY: Belongs to the vitamin uptake transporter (VUT/ECF) (TC
CC       2.A.88) family. Q precursor transporter subfamily. {ECO:0000255|HAMAP-
CC       Rule:MF_02088, ECO:0000305}.
