;GEA2270A is a member of a sulphur-rich heterocyclic peptides
class. All members 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. 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. In addition
cross-linking of a Ser and a Cys-Ser pair usually separated by 7 or 8
residues along the peptide chain produce a pyridinyl ring. 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.  Several isomers are produced. The
structural differences between them lie in the extent of the
modifications, methylation, methoxylation, and oxidation of the
thiazole and oxazole rings, and methylation of asparagine.  The
amidation of Pro-14 probably does not occur by the same mechanism,
oxidative cleavage of glycine, as in eukaryotes.

_pdbx_reference_molecule.description                  
;GEA2270A IS A THIOPEPTIDE CONSISTING OF ONE
PYRIDINE, ONE OXAZOLE AND FIVE THIAZOLE RINGS.
THE OBSERVED C-TERMINAL AMINO GROUP NH2(15) IS
LIKELY TO BE A POST-TRANSLATIONAL DECARBOXYLATED
REMNANT OF A SER C-TERMINAL RESIDUE.
