Protein Details
1. 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.

2. L-rhamnonate dehydratase
General function:
Involved in L-rhamnonate dehydratase activity
Specific function:
Catalyzes the dehydration of L-rhamnonate to 2-keto-3- deoxy-L-rhamnonate (KDR). Can also dehydrate L-lyxonate, L- mannonate and D-gulonate, although less efficiently, but not 2- keto-4-hydroxyheptane-1,7-dioate
Gene Name:
rhmD
Uniprot ID:
P77215
Molecular weight:
44226
Reactions
L-rhamnonate = 2-dehydro-3-deoxy-L-rhamnonate + H(2)O.
