During metamorphosis of leptocephalous larvae of the bonefish (Albula sp.), keratan sulfate, the principal glycosaminoglycan of the extracellular gelatinous body matrix, is degraded. Artificial substrates have been utilized to demonstrate the presence of β-N-acetylglucosaminidase, β-galactosidase and sulfatase activities in whole-body homogenates of early metamorphosing leptocephali. The concerted action of these enzymes has been shown to degrade the keratan sulfate polymer in other tissues… Expand
