Type Comment Proteins
PME5_ARATH developmental stage Expressed throughout silique development (PubMed:16622707). During anther development, expressed from stage 9 to stage 11 in late tapetum, and mature pollen grains (PubMed:21673079).
PME5_ARATH function Acts in the modification of cell walls via demethylesterification of cell wall pectin. Plays an important role in growth of pollen tubes in female floral tissues, possibly via enhancing the interaction between the pollen tube and female floral tissues by modification of the cell walls (PubMed:15659637). May be regulated by MYB80 during anther development and play a role in tapetum and pollen development (PubMed:21673079).
PME5_ARATH pathway Glycan metabolism; pectin degradation; 2-dehydro-3-deoxy-D-gluconate from pectin: step 1/5.
PME5_ARATH similarity In the C-terminal section; belongs to the pectinesterase family.
PME5_ARATH similarity In the N-terminal section; belongs to the PMEI family.
PME5_ARATH subcellular location Distributed in the whole pollen tube, including the plasma membrane and pollen tube wall (PubMed:15659637). Cleaved in the Golgi apparatus by SBT6.1 (S1P) after the Arg-Arg-Leu-Leu (RRLL) and Arg-Lys-Leu-Met (RKLM) motifs. This processing is required for extracellular targeting (PubMed:19144003).
PME5_ARATH tissue specificity Expressed in pollen grains and pollen tubes.
