	2.6.1.36
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.
