ID 2.3.1.296 DE omega-hydroxyceramide transacylase. CA a (9Z,12Z)-octadecadienoyl-containing triacyl-sn-glycerol + an N-(omega- CA hydroxy-ultra-long chain fatty acyl)-sphingoid base = a diacylglycerol + CA an N-[omega-(9Z,12Z-octadecadienoyloxy)-O-ultra-long chain fatty acyl]- CA sphingoid base. CC -!- The enzyme participates in the production of acylceramides in the CC stratum corneum, the outermost layer of the epidermis. CC -!- Acylceramides are crucial components of the skin permeability CC barrier. DR Q8N8W4, PLPL1_HUMAN; Q3V1D5, PLPL1_MOUSE; //
