Protein
Pectin acetylesterase 11
Organism
Arabidopsis thaliana
Function
Hydrolyzes acetyl esters in homogalacturonan regions of pectin. In type I primary cell wall, galacturonic acid residues of pectin can be acetylated at the O-2 and O-3 positions. Decreasing the degree of acetylation of pectin gels in vitro alters their physical properties.
Similarity
Belongs to the pectinacetylesterase family.
