General annotation (Comments)

Function	Acts in the modification of cell walls via demethylesterification of cell wall pectin By similarity.
Catalytic activity	Pectin + n H2O = n methanol + pectate.
Pathway	Glycan metabolism; pectin degradation; 2-dehydro-3-deoxy-D-gluconate from pectin: step 1/5.
Subcellular location	Membrane; Single-pass membrane protein Potential.
Tissue specificity	Expressed in siliques, floral stems and rosettes leaves. Ref.4 Ref.6
Developmental stage	Expressed throughout silique development. Ref.6
Miscellaneous	The PMEI region may act as an autoinhibitory domain and prevent untimely PME activity during transport.
Sequence similarities	In the N-terminal section; belongs to the PMEI family. In the C-terminal section; belongs to the pectinesterase family.
