 | | PRD_000223 | | Name: | THIOSTREPTON | | Formula: | C72 H84 N19 O18 S5 | | Description: | Thiostrepton is a hetrocyclic thiopeptide belonging to the
thiocillin family, consisting of four thiazole, one thiozoline and one
piperideine rings. A modified quinoline linked to main-chain residue 1
and side-chain of residue 12. Post translational maturation of
thiazole and oxazole containing antibiotics involves the enzymic
condensation of a Cys or Ser with the alpha-carbonyl of the preceding
amino acid to form a thioether or ether bond, then dehydration to form
a double bond with the alpha-amino nitrogen. Thiazoline or oxazoline
ring are dehydrogenated to form thiazole or oxazole rings. the
pyridinyl involves the cross-linking of a Ser and a Cys-Ser pair
usually separated by 7 or 8 residues along the peptide chain. The Ser
residues are dehydrated to didehydroalanines, then bonded between
their beta carbons. The alpha carbonyl of the Cys condenses with alpha
carbon of the first Ser to form a pyridinyl ring. The ring may be
mutiply dehydrogenated to form a pyridine ring with loss of the amino
nitrogen of the first Ser. The amidation of Ser-17 probably does not
occur by the same mechanism, oxidative cleavage of glycine, as in
eukaryotes. | | Definition date: | 2012-12-12 | | Last modified: | 2023-09-20 |
