Abstract: | Characterization of reaction products showed that an enzyme (lipolytic acyl hydrolase) isolated from potato tubers could act on endogenous substrates as a galactolipase (E.C. 3.1.1.26), lysophospholipase (E.C. 3.1.1.5) or a ‘phospholipase B’ but not as a lipase (E.C. 3.1.1.3). The affinity of the enzyme for methanol as acyl acceptor (acyl transferase activity) was higher than its affinity for water (acyl hydrolase activity). The nomenclature of acyl hydrolases in plants is discussed. |
