Accepted name: L-lysine cyclodeaminase
Reaction: L-lysine = L-pipecolate + NH3
Other name(s): rapL (gene name); fkbL (gene name); tubZ (gene name); visC (gene name)
Systematic name: L-lysine ammonia-lyase (cyclizing; ammonia-forming)
Comments: Requires bound NAD+. The enzyme produces the non-proteinogenic amino acid L-pipecolate, which is incorporated into multiple secondary metabolite products, including rapamycin, tobulysin, virginiamycin and pristinamycin.
