A PF09182 PuR_N Bacterial purine repressor, N-terminal Domain The N-terminal domain of the bacterial purine repressor PuR is a winged-helix domain, a subdivision of the HTH structural family. It consists of a canonical arrangement of secondary structures: a1-b1-a2-T-a3-b2-W-b3, where a2-T-a3 is the HTH motif, a3 is the recognition helix, and W is the wing. The domain allows for recognition of a conserved CGAA sequence in the centre of a DNA PurBox, resulting in binding to the major groove of DNA [1]. PFAM PF09182
A PF00156 Pribosyltran Phosphoribosyl transferase domain Domain This family includes a range of diverse phosphoribosyl transferase enzymes. This family includes: Adenine phosphoribosyl-transferase EC:2.4.2.7, Swiss:P07672. Hypoxanthine-guanine-xanthine phosphoribosyl-transferase Swiss:P51900. Hypoxanthine phosphoribosyl-transferase EC:2.4.2.8 Swiss:P36766. Ribose-phosphate pyrophosphokinase i EC:2.7.6.1 Swiss:P09329. Amidophosphoribosyltransferase EC:2.4.2.14 Swiss:P00496. Orotate phosphoribosyl-transferase EC:2.4.2.10 Swiss:P11172. Uracil phosphoribosyl-transferase EC:2.4.2.9 Swiss:P25532. Xanthine-guanine phosphoribosyl-transferase EC:2.4.2.22 Swiss:P00501. In Arabidopsis, At the very N-terminus of this domain is the P-Loop NTPase domain [1]. PFAM PF00156
