Protein attributes
| Sequence length | 246 AA. |
| Sequence status | Complete. |
| Protein existence | Inferred from homology |
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. |
| Sequence similarities | Belongs to the pectinesterase family. |
| Sequence caution | The sequence AAF69174.1 differs from that shown. Reason: Erroneous gene model prediction. |
