trisporate biosynthesis GO:0046842 PMID:16043374 PMID:8828234 Biosynthesis of trisporate, a sex pheromone. Trisporate stimulates zygophore (sex cell) development in Mucor mucedo ans presumably in all other mucoraceous fungi including Blakeslea trispora. 4-dihydromethyltrisporate is produced solely by the (+) mating type and released into the environment. (-) Mating types react to the stimulus by directed growth and production of zygophores. 4-dihydromethyltrisporate is taken up by (-) hyphae and converted into methyltrisporate by 4-dihydromethyltrisporate dehydrogenase (TDH). Trisporate is synthesized from methyltrisporate by an esterase. Both enzymatic reactions occur specifically in the (-) mating type. UPa:UPA00170 pathway PMID:4818834 pheromone biosynthesis
