Abstract : This report describes the current status of the investigations on the biogenesis and chemistry of the barnacle adhesive substance. Studies of several enzymes which are located in the mantle tissue and which appear to be closely associated with cement production are continuing. As a result of these studies several sulfatases have been detected histochemically and biochemically in mantle tissues in close association with sulfated polysaccharides, which have also been detected histochemically. At present the data from these studies suggests that barnacle mantle tissue contains an enzyme mediated sulfation system whose activity may result in the formation of sulfated mucopolysaccharides.
