Structural Comparison, Substrate Specificity, and Inhibitor Binding of AGPase Small Subunit from Monocot and Dicot: Present Insight and Future Potential
Figure 4
(a) Structural superimposition of both monocot and dicot AGPase SS structures with the template structure. Blue, green, and red solid spheres show the 1st, 2nd, and 3rd sulphate binding site of AGPase SS. Dotted circle represents the structural superimposition of active site residues in line representation. (b) Sequence alignment shows the 1st, 2nd, and 3rd sulphate binding cavity forming residues and their alignment. In the alignment STS, OSS, HVS, TAS, ATS, SLS, BVS, VF1, VF2, CA1, CA2, and BNS represent Solanum tuberosum, Oryza sativa ssp. japonica, Hordeum vulgare, Triticum aestivum, Arabidopsis thaliana, Solanum lycopersicum, Beta vulgaris, Vicia faba1, Vicia faba2, Cicer arietinum1, Cicer arietinum2, and Brassica napus AGPase SS, respectively.
