Involved in the biosynthesis of monoterpenes natural products related to camphor (PubMed:23058847). Catalyzes the conversion of borneol into camphor (PubMed:23058847). borneol + NAD(+) = camphor + H(+) + NADH kcat is 4x10(-4) sec(-1) with borneol as substrate. Optimum pH is 8-8.5. Optimum temperature is 32 degrees Celsius. Secondary metabolite biosynthesis; terpenoid biosynthesis. Specifically expressed in glandular trichomes of mature flowers. Belongs to the short-chain dehydrogenases/reductases (SDR) family.
