Auto-cleavage and PS decarboxylation activity of E. coli PSD. (A) A schematic of auto-cleavage. Pvl, pyruvoyl residue. (B) LC–MS analysis of PS decarboxylation by PSD1–287. Numbers in the chromatogram correspond to individual PE or PS molecular species: 1–5 represent 36:4, 34:2, 36:3, 34:1, and 36:2 PE (length of acyl-chain:degree of saturation), respectively; 1′-5′ denote for equivalent acyl-chain PS. Scheme of PS decarboxylation is shown on the right.
