Probing the mysteries of lignin biosynthesis: the crystal structure of caffeic acid/5-hydroxyferulic acid 3/5-O-methyltransferase provides new insights.

S-Adenosyl-L-methionine-dependent caffeate O-methyltransferase (COMT, EC 2.1.1.6) has traditionally been thought to catalyze the methylation of caffeate and 5- hydroxyferulate for the biosynthesis of syringyl monolignol, a lignin constituent of angiosperm wood that enables efficient lignin degradation for cellulose production. However

Caffeic acid/5-hydroxyferulic acid 3/5-O-methyltransferase (COMT, EC 1.2.1.68) catalyzes at least two reactions in lignin biosynthesis. Of its two supposed substrates in the lignin pathway, COMT from most sources methylates 5-hydroxyferulic acid (5HFA) with two to three times higher activity than
John M Humphreys et al.
Current opinion in plant biology, 5(3), 224-229 (2002-04-19)
Considerable interest in lignin biosynthesis has been fueled by the many roles that lignin plays in development and in resistance to biotic and abiotic stress, as well as its importance to industry and agriculture. Although the pathway leading to the

Bispecific O-methyltransferase (OMT, EC 2.1.1.68) which catalyses the meta-specific methylation of caffeic acid and 5-hydroxyferulic acid was purified to homogeneity from the developing secondary xylem of aspen (Populus tremuloides). The enzyme was purified by conventional techniques and affinity chromatography on
