Synthesis of type IX collagen: effect of beta-xylosides.
Type IX collagen contains a chondroitin sulfate side chain and therefore may be considered as a proteoglycan. We investigated the effect of beta-xylosides on type IX collagen synthesis. Treatment of chondrocytes with beta-xylosides results in the loss of synthesis of large and small molecular weight proteoglycans, but the synthesis of type IX collagen was unaffected. It is likely that the mechanism of addition of sugar residues to type IX collagen is distinct from that of other cartilage proteoglycans.
