CC   -!- FUNCTION: Acyl-protein synthetase activates tetradecanoic acid. It is a
CC       component of the fatty acid reductase complex responsible for
CC       converting tetradecanoic acid to the aldehyde which serves as substrate
CC       in the luciferase-catalyzed reaction.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a long-chain fatty acid + ATP + L-cysteinyl-[protein] = AMP +
CC         diphosphate + S-(long-chain fatty acyl)-L-cysteinyl-[protein];

CC         EC=6.2.1.19;
CC   -!- PATHWAY: Lipid metabolism; fatty acid reduction for biolumincescence.
CC   -!- SIMILARITY: Belongs to the LuxE family. {ECO:0000305}.
