6-Amino-L-luciferin

Amino analog of L-Luciferin, the less active enantiomer (left-handed form) of the biologically active D-Luciferin, the most popular and versatile bioluminescent substrate. While, L-luciferin plays a biologically relevant role in the biosynthetic pathway of the firefly luciferin system, and can be enzymatically converted into the active D-luciferin, it acts as a weak alternative substrate.
