Abstract: The invention relates to a GDSL lipase, genetically-engineered bacteria and an application thereof. The GDSL lipase is derived from Streptomyces diastaticus CS1801 and its amino acid sequence is as shown in SEQ ID NO.2. After construction of a genetically-engineered bacterium strain, a GDSL lipase is generated through fermentation. Through this enzyme, vitamin A and palmitic acid are converted to produce vitamin A palmitate. The content of the vitamin A palmitate obtained from the conversion is 16.35 mg/L at most. The conversion efficiency is 81.75% at most. This lipase provides a new path to synthesize vitamin A palmitate by the enzymatic method and has an important application prospect.
