FIG. 2.

Homologues of PmtA and Pcs. (A) Alignment of the PmtA homologue from P. aeruginosa PAO1 (PA) with the Pcs from R. sphaeroides (RS). (B) Alignment of the Pcs homologue from P. aeruginosa PAO1 with PmtA from S. meliloti (SM). Identical residues are boxed, and an asterisk indicates the stop codon. The diamonds in PmtA homologues indicate residues corresponding to the consensus motif for SAM-utilizing methyltransferases and thought to be involved in the binding of SAM. The black circles indicate residues comprising the motif for CDP-alcohol phosphatidyltransferases. (C) Hydropathy plots of the PmtA of P. aeruginosa and R. sphaeroides. Hydrophobic residues are depicted above the baseline, and hydrophilic residues are depicted below the baseline.
