The N-Terminal Domain of the Tomato Immune Protein Prf Contains Multiple Homotypic and Pto Kinase Interaction Sites

Abstract

Background: Plant immune proteins display complex conformations. Results: The Prf N-terminal domain forms a homo-dimer, has two binding sites for Pto kinase, and interacts with the Prf leucine-rich repeats domain. Conclusion: The Prf N-terminal domain coordinates multiple domain interactions to control the activity of the immune complex. Significance: Additional resolution is supplied to the Prf-Pto complex.
