Protein

Probable pectinesterase/pectinesterase inhibitor 39

Gene

PME39

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

Acts in the modification of cell walls via demethylesterification of cell wall pectin.By similarity

Miscellaneous

The PMEI region may act as an autoinhibitory domain and prevent untimely PME activity during transport.

Catalytic activityi

Pectin + n H2O = n methanol + pectate.

Pathwayi: pectin degradation
