Protein attributes

Sequence length	524 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

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	Secreted › cell wall By similarity.
Tissue specificity	Expressed in siliques, but not in flower buds. Ref.4
Developmental stage	Expression restricted to early to mid-stage of silique development. Not found in vegetative stage. Expressed in the micropyle area of the ovule just after fertilization. Ref.4
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.
Sequence caution	The sequence AAF16638.1 differs from that shown. Reason: Erroneous gene model prediction.
