Protein

Laccase-15

Gene

TT10

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Lignin degradation and detoxification of lignin-derived products (By similarity). Involved in lignin synthesis in seed coats, in seed coat permeability, in seed germination, and in root elongation. Required for the seed coat (testa) brown pigmentation by mediating the polymerization of proanthocyanidin (tannin) from its monomer precursor epicatechin. Promotes sligthly seed dormancy.By similarity5 Publications

Catalytic activityi

4 benzenediol + O2 = 4 benzosemiquinone + 2 H2O.

Expressioni

Tissue specificityi

Mostly expressed in siliques, particularly in developing seeds. Also detected at low levels in stems, seedlings, and flowers.4 Publications

Developmental stagei

Transcript levels increase during rosette leaves development. In the inflorescence stem, highest levels in the young, developing tip and lowest levels in the basal stem tissues. Strong increase 4 days after fertilization. Specifically localized in developing seed coat (testa). Detected in the endothelium and in the pigment strand at the chalaza zone during early stages of embryo morphogenesis. Later, the activity increased and spread to the outer integument, mostly in the oil penultimate cell layer. Strongly expressed in early aborted seeds and in the transmitting tissue of the silique.2 Publications
