Figure 4.
Structure and active site analysis of AGPase subunits. Maize is shown as an example. (A) The composition and distribution of domain structures and conserved motifs in AGPase proteins are marked and annotated in different colours. Based on the conservation of functional sites, we selected representative subunits for analysis. (B) Stereo view of the active sites of AGPLSs based on the sequence of AGPLS4 and (C) of AGPSSs based on the sequence of AGPSS1. Interaction sites between AGPSSs/AGPLSs and ADP-glucose are linked by broken green lines. Different colour stars and amino acids represent different functional sites. The same site with different amino acids is marked with dots in AGPase subunits.
