Lipases (triacylglycerol acyl hydrolases, EC 3. 1.1.3) are key enzymes in fat
metabolism produced by microorganisms, plants, and animals that catalyze
the breakdown of triacylglycerols to free fatty adds and glycerol. In Y.
lipolytica severaJ genes encoding lipases have been isoiated,LlP2 coding for
a secreted lipase (Pignede et al. 1000) and LlPl and LIP3 encoding two
lipase genes of the carboxylesrerase family (Choupina et al. 1999). Lipase
expression was repressed by glucose and induced by fatty acids and olive
oil.
