Thus, the two substrates of this enzyme are L-threonine and fluoroacetaldehyde, whereas its two products are acetaldehyde and 4-fluoro-L-threonine.
This enzyme belongs to the family of transferases, specifically those transferring aldehyde or ketonic groups (transaldolases and transketolases, respectively). The systematic name of this enzyme class is fluoroacetaldehyde:L-threonine aldehydetransferase.
