    Study Notes

    Fatty Acid Synthase Complex

    • Fatty acid synthase complex in humans is a dimer consisting of two identical monomers.
    • Each monomer contains seven enzymes of fatty acid synthase on one polypeptide chain.

    Enzyme Composition

    • The seven enzymes present in each monomer are arranged in order of their contribution in step II reactions (6 reactions).
    • Enzymes include: acetyl transacylase, malonyl transacylase, ketoacyl synthase, ketoacyl reductase, hydratase, enoyl reductase, and thioesterase.

    Important Interactions

    • The -SH of 4'-phosphopantetheine of one monomer is in close proximity to the -SH of the cysteine residue of the other monomer.
