Fig. 3

In vitro reconstitution and kinetic analysis of Q-glycosylation (A) In vitro reconstitution of galQ34 in human tRNATyr with recombinant QTGAL in the presence (+) or absence (?) of UDP-gal. (B) In vitro reconstitution of manQ34 in E. coli tRNAAsp with recombinant QTMAN in the presence (+) or absence (?) of GDP-man. (C and D) Kinetic analyses of galQ34 (C) or manQ34 (D) formation by recombinant QTGAL or QTMAN with different concentrations of human tRNATyr or E. coli tRNAAsp (upper) and UDP-gal or GDP-man (lower), respectively. The initial velocity of galQ34 or manQ34 formation (nM/s) is plotted as the mean � standard deviation (SD; n = 3). Data are fitted to the Michaelis-Menten equation to yield Km and Vmax values (inset). See also Figures S1, S10, and S11.
