REMARK 400 REMARK 400 GROUP: 1 REMARK 400 NAME: THIOSTREPTON REMARK 400 CHAIN: C REMARK 400 COMPONENT_1: PEPTIDE LIKE POLYMER REMARK 400 DESCRIPTION: Thiostrepton is a hetrocyclic thiopeptide belonging REMARK 400 to the thiocillin family, consisting of four REMARK 400 thiazole, one thiozoline and one piperideine rings. REMARK 400 A modified quinoline linked to main-chain residue 1 REMARK 400 and side-chain of residue 12. Post translational REMARK 400 maturation of thiazole and oxazole containing REMARK 400 antibiotics involves the enzymic condensation of a REMARK 400 Cys or Ser with the alpha-carbonyl of the preceding REMARK 400 amino acid to form a thioether or ether bond, then REMARK 400 dehydration to form a double bond with the alpha- REMARK 400 amino nitrogen. Thiazoline or oxazoline ring are REMARK 400 dehydrogenated to form thiazole or oxazole rings. REMARK 400 the pyridinyl involves the cross-linking of a Ser REMARK 400 and a Cys-Ser pair usually separated by 7 or 8 REMARK 400 residues along the peptide chain. The Ser residues REMARK 400 are dehydrated to didehydroalanines, then bonded REMARK 400 between their beta carbons. The alpha carbonyl of REMARK 400 the Cys condenses with alpha carbon of the first Ser REMARK 400 to form a pyridinyl ring. The ring may be mutiply REMARK 400 dehydrogenated to form a pyridine ring with loss of REMARK 400 the amino nitrogen of the first Ser. The amidation REMARK 400 of Ser-17 probably does not occur by the same REMARK 400 mechanism, oxidative cleavage of glycine, as in REMARK 400 eukaryotes.
