Cytoplasm, perinuclear region {Experimental EvidencePubMed:11283335}. Cytoplasm, cytoskeleton, phragmoplast {Experimental EvidencePubMed:11283335}. Note=During interphase, distributed in a punctate pattern in the perinuclear region. Localized in the forming cell plate during cytokinesis.
Possesses low catalytic activity on indole-3-acetic acid (IAA) in vitro. May transfer UDP-glucose from sucrose synthase to callose synthase for the synthesis of callose at the forming cell plate during cytokinesis. Has high affinity for 4-aminobenzoate. Catalyzes the formation of 4-aminobenzoate glucose ester which represents a storage form of 4-aminobenzoate in the vacuole. Is the major source of this activity in the plant. Also active in vitro on benzoates and benzoate derivatives. {Experimental EvidencePubMed:11042207, Experimental EvidencePubMed:11641410, Experimental EvidencePubMed:18385129}.
