PROBLEM TO BE SOLVED: To provide microbial lipases having selectivity to short or medium chain fatty acids.SOLUTION: Disclosed herein is a modified lipase derived from Candida cylindracea comprising an amino acid sequence with the following substitution (1) or (2), which acts preferentially on short chain fatty acids (C4-C6) in milk fat, most preferentially on C4 fatty acid: (1) substitution of an amino acid corresponding to the amino acid at position 428 of a specific amino acid sequence with asparagine; (2) substitution of an amino acid corresponding to the amino acid at position 429 of the specific amino acid sequence with phenylalanine or methionine.SELECTED DRAWING: NoneCOPYRIGHT: (C)2020,JPO&INPIT【課題】短鎖ないし中鎖脂肪酸選択性を有する、微生物由来のリパーゼの提供。【解決手段】カンジダ・シリンドラッセに由来し、以下の(1)又は(2)の置換が行われたアミノ酸配列からなり、乳脂肪の短鎖脂肪酸(C4~C6)によく作用し、C4の脂肪酸に最もよく作用する改変型リパーゼ:(1)特定のアミノ酸配列の428位アミノ酸に相当するアミノ酸に対する、アスパラギンへの置換;(2)特定のアミノ酸配列の429位アミノ酸に相当するアミノ酸に対する、フェニルアラニン又はメチオニンへの置換。【選択図】なし
