Functions as acyltransferase to form the sinapate ester sinapoylmalate. May rather catalyze a transesterification reaction rather than a hydrolysis. May also have carboxypeptidase activity.CATALYTIC ACTIVITY:1-O-sinapoyl-beta-D-glucose (S)-malate = D- glucose sinapoyl-(S)-malate.ENZYME REGULATION:Slightly inhibited by phenylmethylsulphonylfluoride (PMSF).ALTERNATIVE PRODUCTS:Event=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q8RUW5-1; Sequence=Displayed; Name=2; IsoId=Q8RUW5-2; Sequence=VSP_027464; Note=Derived from EST data. May be due to a competing donor splice site. No experimental confirmation available;TISSUE SPECIFICITY:Highly expressed in seedlings. Expressed in leaves, stems, flowers and siliques, and at low levels in roots.PTM:N-glycosylated.MISCELLANEOUS:Plants lacking SCPL8 do not contain sinapoylmalate and accumulate its biosynthetic precursor, sinapoylglucose.SIMILARITY:Belongs to the peptidase S10 family.SEQUENCE CAUTION:Sequence=AAC17816.2; Type=Erroneous gene model prediction; Sequence=AAK32769.1; Type=Frameshift; Positions=260; Sequence=AAM15006.1; Type=Erroneous gene model prediction; "
