title: A common structure of substrate shared by lignostilbenedioxygenase isozymes from Sphingomonas paucimobilis TMY1009.
abstract: A common structure of substrates of lignostilbenedioxygenases was investigated using synthesized stilbenes. Cell-free extracts of Sphingomonas paucimobilis TMY1009 degraded only trans-4-hydroxystilbene and trans-4-hydroxy-3-methoxystilbene. Other stilbenes that had no 4-hydroxyl group and had a cis structure were not substrates for lignostilbenedioxygenases. These results indicate that a 4-hydroxyl group and trans-structure is necessary for the common structure for substrates of lignostilbenedioxygenases.
