Enzymes

Protein Details
1. Lactaldehyde reductase
General function:
Involved in oxidoreductase activity
Specific function:
(R)-propane-1,2-diol + NAD(+) = (R)- lactaldehyde + NADH
Gene Name:
fucO
Uniprot ID:
P0A9S1
Molecular weight:
40644
Reactions
(R)-propane-1,2-diol + NAD(+) = (R)-lactaldehyde + NADH.
(S)-propane-1,2-diol + NAD(+) = (S)-lactaldehyde + NADH.
Protein Details
2. Glycerol dehydrogenase
General function:
Involved in oxidoreductase activity
Specific function:
Catalyzes the NAD-dependent oxidation of glycerol to dihydroxyacetone (glycerone). Allows microorganisms to utilize glycerol as a source of carbon under anaerobic conditions. In E.coli, an important role of gldA is also likely to regulate the intracellular level of dihydroxyacetone by catalyzing the reverse reaction, i.e. the conversion of dihydroxyacetone into glycerol. Possesses a broad substrate specificity, since it is also able to oxidize 1,2-propanediol and to reduce glycolaldehyde, methylglyoxal and hydroxyacetone into ethylene glycol, lactaldehyde and 1,2-propanediol, respectively
Gene Name:
gldA
Uniprot ID:
P0A9S5
Molecular weight:
38712
Reactions
Glycerol + NAD(+) = glycerone + NADH.

6. 2-keto-3-deoxy-L-rhamnonate aldolase
General function:
Involved in carbon-carbon lyase activity
Specific function:
Catalyzes the reversible retro-aldol cleavage of 2-keto- 3-deoxy-L-rhamnonate (KDR) to pyruvate and lactaldehyde. 2-keto-3- deoxy-L-mannonate, 2-keto-3-deoxy-L-lyxonate and 4-hydroxy-2- ketoheptane-1,7-dioate (HKHD) are also reasonably good substrates, although 2-keto-3-deoxy-L-rhamnonate is likely to be the physiological substrate
Gene Name:
rhmA
Uniprot ID:
P76469
Molecular weight:
28916
Reactions
2-dehydro-3-deoxy-L-rhamnonate = pyruvate + (R)-lactaldehyde.
