Morbidoni, HR, de Mendoza, D and Cronan, JE Jr (1996) Bacillus subtilis acyl carrier protein is encoded in a cluster of lipid biosynthesis genes. J. Bacteriol. 178:4794-800


A cluster of Bacillus subtilis fatty acid synthetic genes was isolated by complementation of an Escherichia coli fabD mutant encoding a thermosensitive malonyl coenzyme A-acyl carrier protein transacylase. The B. subtilis genomic segment contains genes that encode three fatty acid synthetic proteins, malonyl coenzyme A-acyl carrier protein transacylase (fabD), 3-ketoacyl-acyl carrier protein reductase (fabG), and the N-terminal 14 amino acid residues of acyl carrier protein (acpP). Also present is a sequence that encodes a homolog of E. coli plsX, a gene that plays a poorly understood role in phospholipid synthesis. The B. subtilis plsX gene weakly complemented an E. coli plsX mutant. The order of genes in the cluster is plsX fabD fabG acpP, the same order found in E. coli, except that in E. coli the fabH gene lies between plsX and fabD. The absence of fabH in the B. subtilis cluster is consistent with the different fatty acid compositions of the two organisms. The amino acid sequence of B. subtilis acyl carrier protein was obtained by sequencing the purified protein, and the sequence obtained strongly resembled that of E. coli acyl carrier protein, except that most of the protein retained the initiating methionine residue. The B. subtilis fab cluster was mapped to the 135 to 145 degrees region of the chromosome.
