Extended Data Fig. 4: Enzyme kinetic assays of GpPurZ0.
From: Alternative Z-genome biosynthesis pathway shows evolutionary progression from Archaea to phage

Kinetic assays were performed by monitoring increase of absorbance at 287 nm with varying concentrations of one substrate as indicated on X-axis, a-d, GTP, dGTP, dGMP and dIMP respectively, while maintaining the other two substrates in excess. Data are mean ± SEM (N = 3 replicates).
