Fig. 2From: Identification of critical residues of O-antigen-modifying O-acetyltransferase B (OacB) of Shigella flexneriDomain architecture of OacB. Acyl_trans_3 domain of OacB spans from 38 to 372 amino acids. Blast hits identified OacB as similar to OafA (609 amino acids) containing acyltransferase and SGNH-hydrolase domains.
