The enzyme activity of LpsA2 was increased to 250% or above by 1 mmol/L Co2+, Hg2+ and Zn2+, respectively. The activity was also elevated to 110.7% and 138.0% by 15% dimethylformamide and dimethyl sulfoxide, and 352.7% and 189.7% by 0.1% and 1% Span-20, respectively. The enzymatic properties of LpsA2 from S. avermitilis were characterized that may provide the fundament to the screening of bio-engineered bacteria and the industrial applications in food processing and drug synthesis.

avermitilis的脂肪酶基因lpsA2进行了异源表达和酶学功能鉴定，不仅为脂肪酶的研究积累了更多数据，也为具有优良性能的脂肪酶生物工程菌的筛选奠定了基础，更为其在食品加工、药物合成等工业生产中的应用提供了依据。
