Hyaluronate-proteoglycan complex: evidence for separate biosynthesis mechanisms of the macromolecules.

In cartilage cells biosynthesis of hyaluronate and chondroitin-4-,-6-sulfate from proteoglycan takes place via two different distinct precursor pools; the synthesis of hyaluronate appears to require the unaffected formation of nucleotides and nucleic acids, whereas that of proteoglycan is very sensitive to the modulation of protein biosynthesis.
