UniProtKB - Q84UB5 (BSMT1_PETHY)
Protein
S-adenosyl-L-methionine:benzoic acid/salicylic acid carboxyl methyltransferase 1
Gene
BSMT1
Organism
Petunia hybrida (Petunia)
Status
Functioni
Converts benzoic acid into the volatile ester methyl benzoates (PubMed:14630969).
This scent, mostly produced in a rhythmical, diurnal manner, attracts the pollinators (PubMed:14630969).
