Which of the following transfers malonyl group from co-A to ACP?(a) Acyl carrier protein(b) Acetyl co-A ACP transacetylase(c) Enoyl-ACP reductase(d) Malonyl co-A ACP transferaseThis question was posed to me by my college professor while I was bunking the class.Asked question is from Biosynthesis of Fatty Acids and Eicosanoids topic in section Lipid Biosynthesis, Biosynthesis of Amino Acids, Nucleotides and Related Molecules of Biochemistry

Answer» RIGHT choice is (d) Malonyl co-A ACP transferase

For explanation I WOULD SAY: Acyl carrier protein carries acyl groups in thio-ester linkage.
