Comment
A cytochrome P-450 (heme-thiolate) protein. This enzyme catalyses a step in the pathway of abietic acid biosynthesis. The activity has been demonstrated in cell-free stem extracts of Abies grandis (grand fir) and Pinus contorta (lodgepole pine). Activity is induced by wounding of the plant tissue [2].
