2-keto-3-deoxy-L-rhamnonate aldolase also performs a retroaldol reaction on the other products of RhmD 2-keto-3-deoxy-l-mannonate and 2-keto-3-deoxy-l-lyxonate indicating a coupled pathway of assimilation of the RhmD substrates which are likely to be imported using the neighboring transporter homolog RhmT; all three genes appear to be in a rhmRDTA operon with the RhmR predicted transcriptional regulator (Rea, 2008). yfaXWVU is renamed as rhmRDTA (personal communication, J. Gerlt and D. Roper, 2010).
