Chain A   (PQQB_PSEPK | Q88QV5)
biological process
    GO:0018189    pyrroloquinoline quinone biosynthetic process    The chemical reactions and pathways resulting in the formation of the cofactor pyrroloquinoline quinone (PQQ); it is synthesized from a small peptide containing tyrosine and glutamic acid; these amino acids in the peptide are multiply cross-linked and the rest of the peptide is removed.
    GO:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
