Ypc1p can catalyze the reverse reaction , i . e . the condensation of free fatty acids with phytosphingosine or dihydrosphingosine and overexpression of YPC1 or YDC1 can provide enough ceramide synthesis as to rescue the viability of cells lacking the normal acyl - CoA - dependent ceramide synthases .
