Using a variety of pseudosubstrates and a chemically synthesized analog of SCWP, we report here the identification of PatB1 as a SCWP O-acetyltransferase in Bacillus cereus. Additionally, we report the crystal structure of PatB1, which provides detailed insights into the mechanism of this enzyme and defines a novel subfamily of the SGNH family of esterases and lipases. We propose a model for the O-acetylation of SCWP requiring the translocation of acetyl groups from a cytoplasmic source across the plasma membrane by PatA1 and PatA2 for their transfer to SCWP by PatB1. PatB1 is an O-acetyltransferase that decorates secondary cell wall polysaccharides.,Sychantha D, Little DJ, Chapman RN, Boons GJ, Robinson H, Howell PL, Clarke AJ Nat Chem Biol. 2017 Oct 30. pii: nchembio.2509. doi: 10.1038/nchembio.2509.
