Protein

Probable pectinesterase/pectinesterase inhibitor 46

Gene

PME46

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -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

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