Function

Gramicidin (GCDN) is a polypeptide composed of alternating L- and D-amino acids. It is produced by the bacteria Bacillus brevis[1].

  • GCDN S is an antibiotic cyclic polypeptide.
  • GCDN D is a mixture of GCDN A, B, C.

See theoretical model of Gramicidin Channel in Lipid Bilayer.

Relevance

GCDN has bactericidal activity and is used as a topical antibiotic and as topical contraceptive[2].
