Acyltransferase that catalyzes the formation of ester bonds between fatty alcohols and fatty acyl-CoAs to form wax monoesters (By similarity). Shows a strong preference for decyl alcohol (C10), with less activity towards C16 and C18 alcohols (By similarity). Shows a strong preference for saturated acyl-CoAs (By similarity). a fatty acyl-CoA + a long chain fatty alcohol = a wax ester + CoA (9Z)-octadecenoyl-CoA + 1,2-di-(9Z-octadecenoyl)-sn-glycerol = 1,2,3-tri-(9Z-octadecenoyl)-glycerol + CoA (9Z)-octadecenoyl-CoA + hexadecan-1-ol = CoA + hexadecanyl (9Z)-octadecenoate (9Z)-octadecenoyl-CoA + decan-1-ol = 1-O-decyl-(9Z)-octadecenoate + CoA (9Z)-hexadecen-1-ol + (9Z)-octadecenoyl-CoA = 1-O-(9Z)-hexadecenyl (9Z)-octadecenoate + CoA (9Z)-octadecenoyl-CoA + octadecan-1-ol = 1-O-octadecyl (9Z)-octadecenoate + CoA (9Z)-octadecen-1-ol + (9Z)-octadecenoyl-CoA = 1-O-(9Z)-octadecenyl (9Z)-octadecenoate + CoA hexadecan-1-ol + hexadecanoyl-CoA = CoA + hexadecanyl hexadecanoate (9Z)-hexadecenoyl-CoA + hexadecan-1-ol = 1-O-hexadecyl (9Z)-hexadecenoate + CoA hexadecan-1-ol + octadecanoyl-CoA = CoA + hexadecanyl octadecanoate (9Z)-octadecenoyl-CoA + eicosan-1-ol = 1-O-eicosanyl (9Z)-octadecenoate + CoA Belongs to the diacylglycerol acyltransferase family.
