analyses of the hydrolytic products of oligomers , which had labeled d- ( - ) -3-hydroxybutyrate at the hydroxy terminus , showed that the enzyme cleaved only the second ester linkage from the hydroxy terminus of the trimer and tetramer , and acted as an endo-type hydrolase toward the pentamer and higher oligomers .
