Protein

Pectinesterase 1

Gene

PME1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Acts in the modification of cell walls via demethylesterification of cell wall pectin (By similarity). Demethylates protein phosphatase 2A (PP2A) that have been reversibly carboxymethylated by LCMT1. Acts as negative regulators of genes involved in salt stress response (PubMed:28741704).By similarity1 Publication

Catalytic activityi

Pectin + n H2O = n methanol + pectate.

Pathwayi: pectin degradation

This protein is involved in step 1 of the subpathway that synthesizes 2-dehydro-3-deoxy-D-gluconate from pectin.
