2.A.88.8.6
YhhQ protein (DUF165) (encoded within the purine regulon (PurR) (Ravcheev et al., 2002)) (221 aas; 6 TMSs).  It may be a 7-cyano-7-deazaguanine (preQ₀) transporter. PreQ0 is the product of the reaction catalyzed by GTP cyclhydrolase I, important for the synthesis of folic acid, and an intermediate of interest due to its central role in tRNA and DNA modification and secondary metabolism (Zallot et al. 2017).
