MetaCyc Protein Class: a PqqA peptide

Superclasses: a modified protein
a polypeptide

Summary:
PqqA is a small peptide that is used as the precursor for the biosynthesis of the cofactor pyrroloquinoline quinone. The protein contains the sequence motif -E-X-X-X-Y-, that is, an L-glutamate and an L-tyrosine separated by three amino acid residues. The L-glutamate and L-tyrosine residues form a C-C bond at C9-C9a (catalyzed by the enzyme encoded by pqqE), and are then cleaved from the PqqA peptide.

Instances:
pyrroloquinoline quinone biosynthesis protein A (Klebsiella pneumoniae)

SMILES: C([R2])(C(=O)NC([R3])C(=O)NC(CC1(=CC=C(O)C=C1))C(=O)[a PqqA peptide])NC(=O)C(NC(=O)C(CCC([O-])=O)N[a PqqA peptide])[R1]
