Member	Definition	Role
althiomycin	A peptide antibiotic isolated from soil and enteric bacteria. It is a protein synthesis inhibitor which exhibits antibacterial activity against both Gram-positive and Gram-negative bacteria.	althiomycin
enkephalin, leucine	A pentapeptide comprising L-tyrosine, glycine, glycine, L-phenylalanine and L-leucine residues joined in sequence by peptide linkages. It is an endogenous opioid peptide produced in vertebrate species, including rodents, primates and humans that results from decomposition of proenkephalin or dynorphin and exhibits antinociceptive properties.	Leu-enkephalin zwitterion; Leu-enkephalin
enkephalin, methionine	A pentapeptide comprising L-tyrosine, glycine, glycine, L-phenylalanine and L-methionine residues joined in sequence by peptide linkages. It is an endogenous opioid peptide with antitumor, analgesic, and immune-boosting properties.	Met-enkephalin zwitterion; Met-enkephalin
pepstatin	A pentapeptide isolated from Streptomyces testaceus. It is a potent inhibitor of aspartyl proteases.	pepstatin A
substance p	A pentapeptide composed of L-phenylalanine, L-phenylalanine, glycine, L-leucine, and L-methioninamide joined in sequence by peptide linkages. It is a C-terminal fragment of substance P.	L-Phe-L-Phe-Gly-L-Leu-L-Met-NH2
