Sulfotyrosine, an interaction specificity determinant for extracellular protein-protein interactions

V. Stewart, P. C. Ronald

This paper identifies sulfotyrosine (sTyr) as a key determinant of extracellular protein-protein interaction specificity, highlighting its roles in hormone-receptor binding, HIV entry, chemokine signaling, and blood clotting.

Variation and inheritance of the Xanthomonas gene cluster required for activation of XA21-mediated immunity

F. Liu, M. McDonald, B. Schwessinger, A. Joe, R. Pruitt, T. Erickson, X. Zhao, V. Stewart, P. Ronald

The paper identifies the raxX-raxSTAB gene cluster in Xanthomonas species and shows its role in RaxX peptide production, which is required for XA21-mediated immunity but not for peptide hormone activity.

Sulfated RaxX, which represents an unclassified group of ribosomally synthesized post-translationally modified peptides, binds a host immune receptor

D. D. Luu, A. Joe, Y. Chen, K. Parys, O. Bahar, R. Pruitt, L. J. G. Chen, C. J. Petzold, K. Long, C. Adamchak, V. Stewart, Y. Belkhadir, P. C. Ronald

The paper identifies RaxX as a sulfated RiPP that binds the rice immune receptor XA21, revealing its role in bacterial immune activation.

A microbially derived tyrosine sulfated peptide mimics a plant peptide hormone

R. N. Pruitt, A. Joe, W. Zhang, W. Feng, V. Stewart, B. Schwessinger, J. R. Dinneny, P. C. Ronald

The paper shows that a synthetic sulfated RaxX peptide mimics plant PSY peptides to promote root growth and that XA21 recognizes microbial RaxX to trigger immunity.
