All share a macrocylic core, consisting of a nitrogen containing, six-membered ring central to dehydroamino acids and a subset of five member ring structures including thiazoles, thiazolines and oxazoles. The main characteristic of the nosiheptide structure is a general tendency to be more oxidized than the thiostrepton one. No thiazoline, or hydrogenated quinaldic precursor nor tetrahydropyridine rings are present in nosiheptide. All the corresponding rings are unsaturated. Nosiheptide possess an indolic acid ring system that is appended to the side chains of the Ser/Cys and a central 6-membered nitrogen heterocycle produced by cyclization between two corresponding dehydroalanine acids with incorporation of an adjacent carbonyl group. Thiazole formation is by nucleophilic addition of each Cys side chain to the proceeding carbonyl group followed by dehydration and dehydrogenation. HERE, NOSIHEPTIDE IS REPRESENTED BY GROUPING TOGETHER THE SEQUENCE (SEQRES) AND THE ONE LIGAND (HET) NO1. ; _pdbx_reference_molecule.description ;NOSIHEPTIDE IS A HETROCYCLIC THIOPEPTIDE, CONSISTING OF FIVE THIAZOLES AND ONE 3-HYDROXYPYRIDINE RINGS. A MODIFIED INDOLE RING NO1(14) IS LINKED VIA THE SIDE CHAINS OF 3-HYDROXY 3GL(6) AND CYS(8). THE OBSERVED C-TERMINAL AMINO GROUP NH2(13) IS LIKELY TO BE A POST-TRANSLATIONAL DECARBOXYLATED REMNANT OF A SER C-TERMINAL RESIDUE ; _pdbx_reference_molecule.representative_PDB_id_code 2zjp # loop_ _pdbx_reference_entity_list.prd_id _pdbx_reference_entity_list.ref_entity_id _pdbx_reference_entity_list.component_id _pdbx_reference_entity_list.type _pdbx_reference_entity_list.details PRD_000221 1 1 polymer "PEPTIDE LIKE SEQUENCE RESIDUES 1 TO 13" PRD_000221 2 2 non-polymer "MODIFIED INDOLE RING RESIDUE" # _pdbx_reference_entity_nonpoly.prd_id PRD_000221 _pdbx_reference_entity_nonpoly.ref_entity_id 2 _pdbx_reference_entity_nonpoly.name "4-(HYDROXYMETHYL)-3-METHYL-1H-INDOLE-2-CARBOXYLIC ACID" _pdbx_reference_entity_nonpoly.chem_comp_id NO1 _pdbx_reference_entity_nonpoly.details ? # loop_ _pdbx_reference_entity_link.prd_id _pdbx_reference_entity_link.link_id _pdbx_reference_entity_link.link_class _pdbx_reference_entity_link.ref_entity_id_1 _pdbx_reference_entity_link.entity_seq_num_1 _pdbx_reference_entity_link.comp_id_1 _pdbx_reference_entity_link.atom_id_1 _pdbx_reference_entity_link.ref_entity_id_2 _pdbx_reference_entity_link.entity_seq_num_2 _pdbx_reference_entity_link.comp_id_2 _pdbx_reference_entity_link.atom_id_2 _pdbx_reference_entity_link.value_order _pdbx_reference_entity_link.component_1 _pdbx_reference_entity_link.component_2 _pdbx_reference_entity_link.details _pdbx_reference_entity_link.nonpoly_res_num_1 _pdbx_reference_entity_link.nonpoly_res_num_2 PRD_000221 1 PN 1 6 3GL OE1 2 ?
