CC   -!- FUNCTION: In the final step of gramicidin biosynthesis, reduces
CC       the pentadecapeptide-aldehyde intermediate, that is released from
CC       the terminal module of the non-ribosomal peptide synthetase lgrD,
CC       to the final product ethanolamine-containing gramicidin.
CC   -!- PATHWAY: Antibiotic biosynthesis; gramicidin S biosynthesis.
CC   -!- MISCELLANEOUS: The reduction is strictly NADPH-dependent.
CC   -!- MISCELLANEOUS: Linear gramicidine is a pentadecapeptide antibiotic
CC       produced during sporulation.
CC   -!- SIMILARITY: Belongs to the thioesterase family.
CC   -!- CAUTION: Although this protein is said to have a reductase
CC       activity, it clearly belongs to the thioesterase (hydrolase)
CC       family.
