Description L-lysine aminotransferase
Alternative names L-Lysine 6-aminotransferase;
Lysine-epsilon aminotransferase;
L-Lysine 6-transaminase.
Catalyzed reaction L-lysine + 2-oxoglutarate = 2-aminoadipate 6-semialdehyde + L-glutamate.
Cofactor Pyridoxal-phosphate.
Comments -!- The product (allysine) is converted into the intramolecularly dehydrated form, 1-piperideine 6-carboxylate.
The enzyme is involved in L-lysine catabolism. In actinomycetes, this enzyme is specific to the first step of the beta-lactam antibiotic biosynthetic pathway. An enzyme from Sphingomonas paucimobilis has been cloned (see Patel et al., 2000) but the sequence is not available from current primary databases.
