UniProtKB - P14280 (PME1_SOLLC)
Protein
Pectinesterase 1
Gene
PME1.9
Organism
Solanum lycopersicum (Tomato) (Lycopersicon esculentum)
Status
Functioni
Pectinesterase may play a role in cell wall metabolism during fruit growth and development prior to ripening and may be required for preparing cell walls for softening by polygalacturonase during fruit ripening.
Miscellaneous
The PMEI region may act as an autoinhibitory domain and prevent untimely PME activity during transport.
Catalytic activityi
- [(1→4)-α-D-galacturonosyl methyl ester](n) + n H2O = [(1→4)-α-D-galacturonosyl](n) + n H+ + n methanolEC:3.1.1.11
