DESCRIPTION

Also known as SBLE_STABO, sble, lip1. Responsible for the lactonization of acidic sophorolipids (SLs). Catalyzes the intramolecular esterification (ring closure) between the carboxyl group of the hydroxy fatty acid and the hydroxyl group of sophorose C6'' of acidic SLs. Lactonizes acetylated acidic SLs, producing di-acetylated C18:2, C18:1 and C18:0 lactonic SL, and mono-acetylated C18:1 lactonic SL. Does not catalyze the reverse reaction, the hydrolysis of lactonic SL into acidic SL, nor hydrolysis of triglycerides or paranitrophenyl esters.
