A PF14829 GPAT_N Glycerol-3-phosphate acyltransferase N-terminal Domain GPAT_N is the N-terminal domain of glycerol-3-phosphate acyltransferases, and it forms a four-helix bundle [1]. Glycerol-3-phosphate (1)-acyltransferase(G3PAT) catalyses the incorporation of an acyl group from either acyl-acyl carrier proteins or acyl-CoAs into the sn-1 position of glycerol 3-phosphate to yield 1-acylglycerol-3-phosphate. G3PATs can either be selective, preferentially using the unsaturated fatty acid, oleate (C18:1), as the acyl donor, or non-selective, using either oleate or the saturated fatty acid, palmitate (C16:0), at comparable rates. The differential substrate-specificity for saturated versus unsaturated fatty acids seen within this enzyme family has been implicated in the sensitivity of plants to chilling temperatures [2]. The exact function of this domain is not known. it lies upstream of family Acyltransferase, Pfam:PF01553. PFAM PF14829
