Abstract
- International audience; Background: PME and PMEI isoforms are co-expressed in Arabidopsis. Their biochemical interaction is yet to be characterized. Results: The processive activity of AtPME3 is regulated by AtPMEI7 in a pH-dependent manner in vitro. Conclusion: AtPMEI7 is a key component of the regulation of AtPME3 activity in planta. Significance: The tuning of AtPME3 activity by AtPMEI7 brings insights into the control of homogalacturonan methylesteri-fication in plant cell walls.
