CC -!- PATHWAY: Glycan metabolism; pectin degradation; 2-dehydro-3-deoxy-D-
CC gluconate from pectin: step 1/5.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Single-pass membrane
CC protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in siliques, floral stems and rosettes
CC leaves. {ECO:0000269|PubMed:16622707, ECO:0000269|PubMed:9767082}.
CC -!- DEVELOPMENTAL STAGE: Expressed throughout silique development.
CC {ECO:0000269|PubMed:16622707}.
CC -!- MISCELLANEOUS: The PMEI region may act as an autoinhibitory domain and
CC prevent untimely PME activity during transport.
CC -!- SIMILARITY: In the N-terminal section; belongs to the PMEI family.
CC {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the pectinesterase
CC family. {ECO:0000305}.
