This view shows enzymes only for those organisms listed below, in the list of taxa known to possess the pathway. If an enzyme name is shown in bold, there is experimental evidence for this enzymatic activity.
|Superclasses:||Degradation/Utilization/Assimilation → Aldehyde Degradation → Lactaldehyde Degradation|
Some taxa known to possess this pathway include : Escherichia coli K-12 substr. MG1655 , Salmonella enterica enterica serovar Typhimurium str. LT2
Expected Taxonomic Range:
Anaerobically, (S)-lactaldehyde is converted into (S)-propane-1,2-diol by a reversible reaction catalyzed by EC 22.214.171.124, lactaldehyde reductase. Escherichia coli excretes L-1,2-propanediol into the medium, possibly by facilitated diffusion [Zhu89].
Currently two unrelated genes are known to encode such enzymes in different organisms. In Escherichia coli the enzyme is encoded by fucO gene [Chen84a] (known as rhaO in other organisms [Patel08]), in Salmonella enterica enterica serovar Typhimurium str. LT2 it is encoded by the rhaZ gene [Rodionova13a].
Superpathways: superpathway of fucose and rhamnose degradation
Variants: L-lactaldehyde degradation (aerobic)
