WebWhen onions (Allium cepa) are chopped, cells are broken, propanthial S-oxide (lachrymatory factor; LF) is released and it makes our eyes water. LF had long been believed to be formed non-enzymatically from 1-propenesulfenic acid (PSA), a putative reaction product of alliinase acting on trans- (+)-S- (1-propenyl)-L-cysteine sulfoxide (1-PRENCSO). WebNov 5, 2024 · LFS is the key enzyme that catabolizes hydrolyzed isoalliin into the characteristic propanthial S-oxide (lachrymatory factor) in Allium crops. We classified the LFS gene family into four groups, LFS-a, LFS-b, LFS-c, and LFS-d, according to their phylogenetic structure annotated in three major Allium crops (Fig. 4d). magellan 3000t software https://msledd.com
